Are add-ons keeping you on Firefox 3.6?

Since we implemented Add-ons Default to Compatible, most add-ons that were updated to work on Firefox 4 continue to work on the latest releases. The add-on compatibility problems we’ve had ever since have been minimal.

However, there are still a number of popular add-ons that weren’t updated for the switch to Firefox 4. People who still have these add-ons installed may be skipping Firefox updates because their add-ons are not compatible yet, and probably never will be. As we make a stronger push to move users away from old and potentially insecure Firefox versions, we need to make sure they don’t lose the add-ons they love.

Luckily, we have an amazing add-on developer community, where no abandoned add-on goes unforked. I spent a great deal of time looking for the most popular add-ons still in use on 3.6 and lower, as well as their best alternatives. Here they are.

  • Mr Tech Toolkit. I tried to get in touch with the developers to no avail. They have an updated version available on their site. I normally wouldn’t recommend non-AMO add-ons, but I reviewed the current file (toolkit.xpi, version  and everything looks good, except for a few features that appear to be broken. If you use this add-on, I’d like to hear which of its features you use.
  • Snap Links.  Compatible alternative: Snap Links Plus.
  • Gmail Notifier. Compatible alternatives: WebMail Notifier, GMail Checker.
  • RapidShare DownloadHelper. Compatible alternative: Rapidshare Helper. This add-on hasn’t received full approval, but it doesn’t appear to have any major problems.
  • Bahasa Indonesia (ID) Language Pack, Estonian Language Pack. You can download the latest Firefox already translated to this language (and many more!) from the International Versions page. Just install it over your current Firefox install and you won’t lose any bookmarks or data.
  • 1-Click YouTube Video Download, YouTube Download, Flash Video Resources Downloader. We have many YouTube downloaders listed on AMO, and I specially recommend Video DownloadHelper.
  • MinimizeToTray Plus. Compatible alternative: MinimizeToTray Revived.
  • Update Notifier. Compatible alternative: Add-on Update Checker.
  • Full Fullscreen. Modern versions of Firefox already hide toolbars in a similar way. There are some kiosk applications listed on AMO, though we normally don’t allow them to get full review.
  • Noia 2.0 (eXtreme). Compatible alternative: Noia 4.
  • PDF Plugin for Firefox on Mac OS X. Compatible alternative: PDF Viewer, a.k.a pdf.js, created by Mozilla Labs and possibly coming soon as part of Firefox.
  • CacheViewer. Compatible alternative: CacheViewer Continued.
  • CustomizeGoogle. I couldn’t find an exact match, but you should try Google Minimalist and SearchTweaker. There are many more, of course.
  • Ad blocker. Compatible alternative: Updated Ad Blocker. And the always popular AdBlock Plus.
  • CuteMenus – Crystal SVG. Compatible alternative: Menu Icons Plus.
  • Mouse Gestures Redox. Compatible alternatives: All-in-One Gestures and FireGestures.
  • 1-ClickWeather, Forecastbar Enhanced, WeatherBug. Compatible alternative: Forecastfox Weather.
  • Easy DragToGo. Compatible alternative: DragIt.
  • Organize Status Bar. Since the status bar was replaced with the Add-on Bar in recent versions or Firefox, you can reorganize all of your buttons and toolbars in one place. This extension isn’t necessary anymore.
  • Chromifox Basic. Compatible alternative: FXChrome.
  • Fox Splitter (formerly Split Browser). The add-on was forked by the developer into the new Fox Splitter. You should uninstall the old version and install this new one.
  • Splash. This add-on displays a splash window before Firefox loads. Understandably, there are no known alternatives. Why would you want to slow down Firefox load time for this? I’d love to know…
  • Smart Bookmarks Bar. Compatible alternatives: Roomy Bookmarks Toolbar and Smartest Bookmarks Bar.
  • SQLite Optimizer. This add-on is generally unnecessary. The largest local DB in your profile is usually the Places DB, and that one is vacuumed when necessary. Other add-ons that handle very active DBs should do the same.
  • Clipmarks. Compatible alternative: Evernote Web Clipper.
  • Auto Shutdown. Compatible alternative: Auto Shutdown NG.
  • AnyColor. The very new Colorlicious covers its most important features. We also recommend giving Background Themes (Personas) a try.
  • Print Preview. Compatible alternative: Print Preview (Update).

I’d like to thank the developers of FireDownload, IE Tab and The Browser Highlighter for upgrading their add-ons between the time this list was compiled and the publication of this blog post.

Are there any other add-ons holding you back on Firefox 3.6 or older? Do you have other recommendations for alternatives? Let me know in the comments!

    The Add-on (Organize Status Bar) still has usefulness,

    Regarding the add-on (Organize Status Bar) for those that have moved on to Fx4+ or newer, but continued to use their incompatible add-ons that work on Fx4+ without problems. (Organize Status Bar) is useful in rearranging the order of those add-ons with old status-bar icons that haven’t been converted to movable toolbar buttons.To my knowledge there still isn’t any alternative add-on that allows you rearrange the order of those old status-bar icons on the Add-on bar’s status-bar compatibility shim.

    1. Jorge Villalobos wrote on :

      I don’t think it’s possible to create such an add-on, since you would either need to limit the customizable area to the statusbar compatibility shim, or figure out a way to mix statusbar buttons with Add-on Bar buttons, which would be really difficult to do.

      I would expect most add-ons to have migrated to the new way of placing buttons below the content, though ironically my own add-on still doesn’t do this :(.

      1. rob64rock wrote on :

        Yes, your add-on ( is one add-on that I still prefer to use it’s old status-bar icons since they’re simply more compact which doesn’t take up to much toolbar space than the alternative toolbar buttons on the toolbar.

        Using add-on (UI Fixer) allows me to move the (old status-bar compatibility shim) to what ever toolbar I choose and add-on (Organize Status Bar) allows me to rearrange those old status-bar icons in the order of my choosing.

        Now if someone could combined both above add-on features into one add-on, I would have one less add-on to worry about.

        Note: I just hope you will never remove the old status-bar icons from any time soon.

        1. Jorge Villalobos wrote on :

          If we ever update again, and I hope we do, fixing the icons is our top priority. The icons would be smaller as the current toolbar icons, but probably bigger than the current statusbar icons.

    Add-on for xforms and compatibility with slingplayer is keeping me at 3.6.

    1. Jorge Villalobos wrote on :

      For XForms, there is a beta version available that works on Firefox 4 but not on later versions. The add-on and the idea behind it have been abandoned. I don’t know anything about slingplayer, though. What does it do? Is it an extension or a plugin?

      1. Philipp wrote on :

        I can only second Jorge, the Mozilla XForms addon will not be developed any further (and fixing it for the current Firefox versions proved to be way too much work). Server-side solutions such as Orbeon or BetterForms or different client-side solutions such as XSLTForms are better and more future-proof alternatives.

      1. Jorge Villalobos wrote on :

        The Mozilla Labs team decided to focus on other projects, and there wasn’t enough developer interest to keep it alive. If a developer was willing to take over the add-on and update it to modern Firefox versions, I think we would all be very happy to accept those patches.

  6. Caspy7 wrote on :

    Would be awesome if a user visited a page for an addon not compatible with the latest Firefox (or if they could be notified even more conveniently) that there were recommendations for similar addons.
    Hmm, what about an ‘Alternatives’ Group where people create groups that contain alternative addons & if you’re visiting that addon it pops up? Dunno if this is possible…

    1. Lozzy wrote on :

      +1. I’m not sure why AMO doesn’t already have a feature for user suggested alternatives.

    2. Gervase Markham wrote on :

      Seconded. This should be a built-in feature of AMO, where Mozilla can recommend an add-on as an alternative to one which has not been updated for e.g. 3 releases. If the addon author doesn’t like the recommendation, they can update their add-on or provide their own recommendation.


    3. Jorge Villalobos wrote on :

      That’d the nice to have, certainly, though I suspect in many cases there would be no user-provided recommendations because there are none. FWIW, I did modify the descriptions of most add-ons listed in this post to point to the recommended alternatives (after notifying the developers, of course).

      1. Ken Saunders wrote on :

        Well, perhaps one way to handle this if something were to be done at all would be to add a “Search for similar add-ons” link/feature to add-ons marked as incompatible. Maybe pull from the add-on’s description, keywords, category, and/or tags (if they have any)?
        It’s probably the only way to offer generated alternatives and least it isn’t a solid dead end for users. Besides, it just isn’t realistic to expect an exact alternative since most add-ons are unique.

        The site’s search suggestions function works well in my experience so encouraging the use of it and even more so, bringing back advanced search would be helpful.

        It took me a long time to get into this mindset, but unless an add-on is massively popular, then they all have the possibility of being temporary. It’s just due to the fluid nature of Firefox.

        I do appreciate the value of bootstrapped add-ons now. I just wish that there were more options like adding XUL overlays and more documentation and examples. Like with XUL School. 🙂

  7. pingswap wrote on :

    I’m quite unhappy that the keywordManager add-on ( doesn’t work in current firefox versions. There doesn’t seem to be an alternative (do you know one?) and besides I can’t believe this isn’t an out-of-the-box functionality.

    1. Jorge Villalobos wrote on :

      I looked around and couldn’t find an equivalent add-on. To be honest, I don’t see how this add-on is all that useful. You can group all of your keywords in on Places folder, or tag them so that they are easy to locate and manage. Judging by its usage stats, it isn’t very heavily used, so I don’t think it warrants being a shipped feature.

  8. Lozzy wrote on :

    RIP Mouse Gestures Redox too. That’s the one addon I really miss, Firegestures doesn’t hold a candle to it.

    1. nrj wrote on :

      The most recent Mouse Gestures Redox nightly still works just fine for Firefox 7 and up (on 13 right now). The main site is down so I can’t find an XPI to install for you but I’m sure there’s a copy out there.

    2. Jorge Villalobos wrote on :

      I should point out that the add-on was removed from AMO due to security vulnerabilities related to how they manage their custom gestures handlers. I think the add-on was safe to use as long as you didn’t install untrusted custom handlers from the web.

  9. Ken Saunders wrote on :

    Jorge, it was -really- cool of you to take the time to do this.

    @Caspy7 and Lozzy, it wouldn’t be a bad idea for someone, or some people to volunteer to do that.
    It could be as simple as creating an add-on collection or, an entire site/blog/community dedicated to it and also perhaps to finding people to take over the development of abandoned add-ons that don’t have alternatives. I would do it personally, because it’s a good idea and there’s a need for it, but I don’t have the time.

    I started a site with some other volunteers to provide a specific service to a particular segment of Firefox users because I saw a need for it and didn’t expect Mozilla to do it because they/it have many other things to focus on.
    In fact, people do this sort of thing all of the time.

    1. Jorge Villalobos wrote on :

      It’s possible that you just need to rebuild the add-on with a new version of the SDK for it to work with a recent version of Firefox. The main problem would be to get the devs to accept it and publish it, I guess.

  12. HarzG wrote on :

    I use EasyGestures, but there are no recent activities on his site unfortunately. The great advantage of eG is that I can forget all gestures like LRD etc. for any actions because the pie show me what I can do. The list of features is very long imho, but I can also use a part of them by downsizing the visible ones.
    It’s a pity that there isn’t an active developer or an “assistant to” for eG. But I can understand any developer who decided to quit -> Mozilla’s choice to start a very rapid development. Anybody who has other priorities (like work, family, house) can’t spent every month a lot of time to beta-test a new FF/TB-version with his add-on.

    I read that Mozilla let add-ons work if they won’t crash the application.
    But I know also that the “let it work, if …” could be a security issue to accept older add-ons (third party or former Moz-listed) if they are no (longer) listed on the Mozilla-add-on-site.
    Maybe Mozilla should warn anytime about any “founded, but not Moz-listed” add-on (even if the rdf-info told the installer 500.0.*) to tell users again “it’s not from Mozilla, do you know enough about the risc’s?”

    Some people like me used in the past q&d-hacks to let an add-on work as usual. So I edited a time ago some install.rdf-files and made “my own” add-ons installable for the new TB/FF-releases.
    Use Mozilla by any upgrade a “not Moz-listed”-control even if the “third party”-add-on tell FF/TB about a larger in the rdf-file than the Mozilla-release is?

    1. Jorge Villalobos wrote on :

      Default to Compatible works for both Mozilla-listed and non-listed add-ons. The main “if” that we have is that the add-on can’t have binary components, because those break with every new release. Binary components are very common for non-listed add-on, which is why it looks like we don’t allow non-listed add-ons to be compatible by default. However, we do.

  13. chiaro wrote on :

    One of the reasons that users may chose to stay with Firefox 3.* is that there is a documented Bug in all later Versions of Firefox (post Firefox 3.”)

    It would be a great incentive for users to use later Versions of Firefox if this Bug were addressed.

    Even without a test case, the bug is quite clear and there was a previous test case with an identical issue

    It would be a great step forward (and incentive to use later versions of Firefox) if this Bug could be resolved

    Many thanks

    1. Jorge Villalobos wrote on :

      I doubt it. If this were a major bug, there would be tons of people piling up on that bug, or similar ones. Furthermore, you were asked to provide a test case more than a year ago and none was provided. If you want the bug to be fixed, you need to help us get it fixed.

    Firefox Throttle

    I upgraded from 3.6 a while ago, but Firefox Throttle was the one add-on that made leaving 3.6 hard.

    Firefox Throttle allowed the user to limit Firefox’s download and upload speeds.

    As someone who often shares a internet connection, it was a very easy to use way of ‘playing nice’ and not using all the download/upload bandwidths while surfing the ‘net, especially when using the PortableApps Firefox (3.6) Portable on other peoples connections.

    I’ve looked for similar a add-on to no avail. I guess there is not much of a demand for a way to slow down websurfing with Firefox :-p

    Jorge, thank you for this blog/post and for asking us about our favourite add-ons that didn’t make it past 3.6.

    1. Jorge Villalobos wrote on :

      There are a bunch of add-ons listed on AMO that help you keep track of your bandwidth usage. However, they are mostly tied to specific ISPs. Some, like Minimeter, support a wide variety of ISPs, so maybe it’ll work for you.

      I didn’t find any add-ons that could throttle the upload / download speeds, though. Actually, I wonder how Firefox Throttle works, because I can’t imagine what you could do to accomplish that.

I recommend that you encourage the developers to switch to the Add-on Bar, which should be relatively easy to do.

    On one side we hear the Mozilla eco system of app and extensions is important and a main differentiator, and the many Mozilla development requests have to be respected by the extension developers (eg. fast startup) then on the other side, why have tools for extension development such a low priority?

      Yeah, I agree with you 100% that we need to do a much better job when it comes to add-on developer tools. That’s definitely something we’re aware of and we try to improve on.

    Great article. I’m of the opinion that great and even good extensions will be kept up to date, and even if they aren’t, the very nature of the open source community will ensure that the idea is ported forward.

    I’d just like to point out that I actually don’t use Firefox. I use Pale Moon, because while Firefox is offered as optimized for Linux and OS X on those platforms, and 64-bit binaries are available, Firefox for Windows is rather bland. No optimization and no 64-bit. Truth be told I don’t see real-world benefit, so I don’t blame Mozilla, but it’s nice to know.

    I took Coloricious from your list and added it. I don’t think I’ll keep it for very long, but right now, the green theme I made is nice.

    A potential better alternative to CuteMenus is Mar Mod. It adds the icons, but it does a lot more than that.

    Anyone who wants a splash screen can pick up Portable Firefox from They sometimes take up to a week to get browser updates out, but sometimes they’re out the next day. Pale Moon users can similarly use Pale Moon Portable, from the official Pale Moon site. Both Portable browsers get a splash screen, and I think you can configure both by poking around in the launcher files. “Portable” browsers are not meant to be used as regular ones, but nothing stops you from doing so. (Just know that you have to manually move or copy your profile to the portable browser’s directory, and copy the various plugins, like Flash, to the appropriate directory.) Also, Portable Firefox removes the profile manager. Not sure about Pale Moon. I don’t think they add a delay, they just get tossed up when the launcher starts. The launcher itself may add a delay, but if it does, it isn’t noticeable on three computers I’ve used it on. A couple old Intels (Pentium 4 HT and Pentium D) and a (semi) modern AMD dual core.

    TabSidebar was my favorite add-on on FF3.6.
    It is an extension that puts tabs thumbnails on sidebar
    and let u handle it from there (stop/refresh, close/open, back/forward).

    As FF4.0+ got into our life TabSideBar has broken.

    I was very happy when ElectronPlumber took it under his hand
    and pulished TabSidebar Reloaded 1.0.
    He released it once on AMO but it was removed from there for some reason.

    I’ve crossed the net to find a working link to the extesion and i found it.

    now everyone can enjoy it:

    The addon I miss most is WebExposed 1.0.7. It was a terrific ultra-lightweight SEO analysis tool that I used constantly because the continuous basic info ran in my status bar (now have Status4evar) as I browsed and one click would pop a sidebar with all the info that I personally prefer to see when doing a quick check of a site. I loved how it ran constantly with info in the status bar because you never know when you’re going to cross a site, while generally browsing, whose info could be really useful but you would never realize it without the “starter clues” flowing by in the bottom.

    It was perfect!!! And no one has made anything comparable to it that I can find; they’re all either too heavy to continuously run while browsing, or too scant on info, or require taking additional steps to get info everytime you realize you want to check a site…and none of them run the same way as Web Exposed with any/all the same selections of useful info.

    I contacted the developer a few months ago to ask if he was going to update and he said he was not continuing support. He was thinking of putting the addon up for sale to anyone that wanted to buy it & update it themselves. I sincerely hope someone does and that FireFox will notify us about the update!

      There are several SEO add-ons on AMO, many of which display their info in the Add-on Bar. I see that you’ve looked into them already. Is there anyone that is close to what you need? Have you tried contacting any of their developers?

          Most of those appear to still work in recent releases, but I don’t have the time to check all of them. I see a couple that were mentioned in this post, so perhaps you should switch to the alternatives to minimize the compatibility impact.

          As for the rest, if you can tell me which ones are necessary for you and don’t work in Firefox 12 or 13, I can look into alternatives for you.

          1. para wrote on :

            i dont know which don’t work in Firefox 12 or 13. i quit trying to update firefox long ago because of addon incompatibility.
            which ones are necessary? i suppose they are all necessary and none of them are necessary, but i uninstall the ones i don’t use.

            we could look for alternatives, but then how long till they become incompatible as well?
            what i want to know is why firefox does this? how many hundreds or thousands of hours of addon programming have they destroyed? why cant they stop? cant they release updates themselves in the form of an addon?

          2. para wrote on :

            and most importantly, when will they stop making updates that break addons – so i know what verson i can finally update to.

          3. Jorge Villalobos wrote on :

            Most add-ons that were updated past version 4 will continue to be compatible for a very long time, since every new Firefox version is a very small, incremental change that breaks very few things in terms of add-on compatibility.

            Also, Firefox now assumes add-ons are compatible and doesn’t check their compatibility metadata, so developers don’t need to update their add-ons all the time just to declare them as compatible. This is why I think it would be better for you to look for alternatives now, instead of sticking with an unsupported and insecure version of Firefox.

  37. njw wrote on :

    I was completely stuck on Firefox 3.5x as I used an add-on call BookMark Previews (
    that was not compatible with any later versions.

    There is absolutely no alternative addon at all that has the “carousel” view of the bookmark thumbnail images.

    I so desperately needed this addon, that I actually edited it to get it to work on FF12. I have put the details of my edit on the addons page, but I don’t have the ability to tidy it up to release as an official addon on Mozilla

    I have graphics missing, my home page won’t stay put and browser is even SLOWER than when I was avoiding FF12. In former times, updating eliminated the slowdown. I have faded portions of site addresses as well. Moving the symbols around on my toolbar is not appreciated.
    I feel for all these folks whose add-ons are gone. I thought it was bad enough to lose Real Player.

      There’s a new version in the developer’s homepage. It was submitted some time ago to AMO, but was rejected due to a relatively minor issue. I’m trying to contact the developer to get this fixed and get the new version up on AMO.

    A while back I fell for one of the suggestions to upgrade to Firefox 4.0 and was quickly sorry. One of my most-used add-ons, cookie swap. was not compatible with ver 4.0. I had a devil of a time getting rid of 4.0 and switching back to 3.6. Now I am leery of any upgrades.

    No, add-ons were not, but my development schedule and work needs were. at work I am the admin for Atlassian’s Jira and Confluence and we are running on versions that are not supported on Firefox higher than 3.6. We had plans to upgrade but now you’ve broken our usage of FF within our organization.

    My company also creates web applications and we have to plan testing and development changes accordingly. We cannot just absorb browser updates when you decide it was mandatory. It was annoying that i could not suppress the “do you want to upgrade now” messages and now that you’ve just forced the upgrade on me is incomprehensible.

    You have now taken down my employees usage of firefox, I can not allow them to run an unsupported browser either in our development testing and specifically not with . What gall, dare I even say Microsoft doesn’t force me to upgrade the browser until I am ready.

      You can continue using 3.6, as long as you disable automatic updates.

  43. Charles wrote on :

    No. It is the terrible use of memory that all versions of FF after 3.6 suffer from! I use basically three add-ons (Adblock Plus, Tabs Mix Plus, Forecast Fox). Those three I must have! I would love to use more but, every post on some forum about how slow FF is, or how much of a hog FF is, or some similar complaint is met with the pat answer “start by disabling your add-ons, then one-by-one enable them to identify the culprit.”

    What a load of BS — it’s FireFox, not the add-ons. Tab Candy causes the browser to crash without fail — I don’t even try to use it anymore. 8-10 tabs seems to be the limit with FF 12. With 3.6 I could easily open 20 tabs. FF 12 with MS Security Essentials = constant HDD use and a high-pitched noise. Kill either one and the noise would stop. Kill MSE and I could use FF again.

    I just upgraded to 12.0 and now it wants to upgrade to 13.0 — seriously?!? When does 19 come out – next Tuesday? I am going back to 3.6!

    This browser is a tool – not a toy!

      Sorry to see you’re having these problems, but I can assure you that it’s not the normal experience for these versions of Firefox. Which is good news because it means there should be something to do to fix it. If you haven’t already, head over to and create a support request. Make sure to include the crash IDs (there should be instructions on the site).

      If you already have done that, please reply with the link to your thread so I can make sure it gets attention.

    I have 52 add-ons enabled, usually more (this is a new profile), they’re not lightweight ones by any means and I usually have 10-18 tabs open and Firefox (13) is fast and responsive on a very modest computer with an awful OS.
    Does it use a lot of memory? Sure, but it uses it wisely, it’s much less than Chrome, I don’t stare at the numbers, and I can still run 3 different versions of Firefox -at the same time- as well as other applications like Thunderbird, Inkscape, Photoshop, and my PC runs just fine.

    The Internet is always moving forward. You can choose to stay behind with old, obsolete software, but you’d be vulnerable and missing out on new technology.
    As far as updates, a new version of Firefox is released every 6 weeks now. The majority of people have already gotten used to it and appreciate the benefits. Add-ons are compatible by default now so there’s less breakage with new versions of Firefox.

    It may be a radical change going from 3.6 to the latest, but at some point, you’ll have to just rip the band-aid off and go for it and adjust.

    I hate this new product.. I lost access to the Options controls and all the familiar other parts of 3.6.
    3.6 worked fine for me and I kept pushing off updating until it finally did without my direct desire.

    thanks Mozilla for pushing me to Chrome.

    Charter says that my QuickTime plugin needs updated, But I have updated QuickTime to latest.
    However, I can get my email using browser IE8 or Google Chrome.
    So apparently there is some problem with Firefox.
    I’ve used Firefox for probably 8-10 years and would like to continue.
    So I need some assistance from Firefox to fix the problem.

    “Send page by email” is a much missed add-on. There is and never was anything like it. Plenty of extensions that send text from webpages, or a link to it etc, but nothing as far as I know that actually sent the whole page via email to whoever you wanted – indispensable for providing a record of what a page said. I would change browsers for anything with this functionality (well, anything except for IE)
