Helping You Find Compatible Extensions

We are getting lots of support requests for finding replacement extensions in the comments section. We can provide better support for this in the forums, so we are shutting off comments here. This thread is where you can see what the community has already suggested, as well as post your own support request.

If you’re a Firefox 57 user (aka Firefox Quantum, released November 14) with legacy extensions installed, there is a feature to help you find compatible replacements.

In the Add-ons Manager (Tools menu > Add-ons), click on “Show legacy extensions” to see a list of your incompatible extensions.

Click on “Find a Replacement”, and you will be taken to the AMO page of a compatible alternative.

If an exact replacement hasn’t been identified, you will land on the Featured Extensions collection, which lists only compatible extensions.

For legacy tab extensions that couldn’t migrate at this time because of unavailable APIs (some of which are being developed and prioritized for release in the coming months), the “Find a Replacement” button directs you to a curated collection of compatible tab extensions.

Not Too Late to Migrate

For developers of legacy extensions who may be in the process of migrating, or have plans to do so in the future, please note that once your extension is compatible, your users will no longer be prompted to find a replacement, and your current users will automatically get the updated version.

So you may still want to update to the WebExtensions API, even if you didn’t get it done in time for Firefox 57. For more information on how to migrate legacy extensions, please see this guide.

If You Need Them a While Longer

We understand that some of you won’t be able to find replacements for your legacy extensions. If you want to use them a while longer while you wait to see if they will be updated by their developers, your best option is Firefox ESR 52. This release is updated for security only, and should work with legacy extensions until the release of Firefox 59, which will also update the ESR release to Quantum.

      After all those numerous comments (whatever they might say), let’s try to be constructive:
      Anticipating all those changes, I decided to let the dust settle for a while and see what’s going on.

      I fully understand a lot of Add-on need time to rewrite their stuff; … so I will patiently wait they do
      their stuff BEFORE I upgrade!!!

      The pb is after a bit of investigation some contributors have decided to throw the towel and let their
      program go. The key point is to know which is which. It would be helpful for us regular end-users to
      have a rough honest statement of the progresses.

      This being written, the deciding factor for me to upgrade or not is to be certain there will be an upgrade
      (or an acceptable replacement) for the following Add-ons:
      – Hide Tab bar with 1 tab 1.51
      – Hide Navigation bar 1.42

      For the rest I am willing to take the risk and the burden of a roll-back if not happy.

      Any help or hints would be greatly appreciated.

    3. migol wrote on :

      You are seriously damaging the appeal of Firefox over Chrome! The rich availability of extensions in Firefox has received a large blow, by turning lots of useful extensions obsolete with the new Firefox Quantum. I have been using Firefox and Chrome, where Firefox has been the default browser, mainly because of some extensions which were more feature-rich than the equivalent ones on Chrome. Now, if this situation persists for some time, I will have no reason to keep using Firefox as my main browser, as most users have been migrating to Chrome.
      Another point is that the search for Firefox add-ons has become cumbersome. The groupings (classifications) are much to broad, forcing me to search. When I search for “screenshot” I get a meager result now, with a small list of add-ons having only 100 or so users (instead of the hundreds of thousands in the past), and if I want to open a particular add-on in a new tab (like I did in the past) I cannot; it will open in the current tab only, but then, when I go back to the previous page (using the back button) the text I had written in the search box has gone, forcing me to write again “screenshot”, to obtain again the list I was probing. Very, very unwise to have changed a fantastic firefox addons web site into a mediocre one!
      What are you doing with your product ?

      Hi Sandy, I can definitely understand why you are upset, and while we may not be able to find replacements for all of your extensions, I’d like to try to help you recover your bookmarks.

      If your bookmarks bar is missing on the toolbar, here are some instructions for how to restore it:

      You can also recover missing bookmarks from a backup:

      For ‘Save to Read,’ you might want to try Pocket (, which is fully integrated with the Firefox browser.

      For “Speed Dial,” you might want to try Speed Dial [FVD]. It may not have all of the features of the original Speed Dial, but the developers are continuing to improve and maintain the extension.

      Are there any other extensions you had installed that we might be able to help find replacements for?

        Is there a way to make the font size larger on the Tabs and the Bookmarks bar? It is extremely hard to read, especially for us older people!
        Since “Theme Font & Size Changer” is no longer compatible, do you offer another option for us to be able to increase the font size in these areas? I have only found where I can increase the font size on web pages but not on the Tabs and Bookmarks bar.
        Help Please!!!
        Thank you!

        1. Caitlin Neiman wrote on :

          Hi Barbie,

          We’ve heard from a few folks that the font sizes for the bookmarks bar and tabs are too small to read easily, and I really apologize for that. Our user interface team is working on some ways to address this, but those improvements won’t be available for a few more months. 🙁

          That having been said, there are two short term solutions you might want to try to adjust font sizes. One, you can increase the font size on your operating system and make everything bigger.

          Two, you can modify Firefox’s configuration settings. Accept the warning to continue. Open a new tab and go to ‘about:config.’ Then, search for ‘layout.css.devPixelsPerPx’ in the search box. Double click on the ‘Value’ (which will likely be -1.0). Set a new value that you find appropriate. For example, a value of 1.25 will zoom all of Firefox to 125%. You can right click on the value and click ‘reset’ to go back to the original value at any time. When you are done, close the tab.

          This is not as elegant as Theme and Font Size Changer because it makes everything in Firefox bigger, but hopefully it will be of help until a better solution can be made.

            Hi Terri,

            It looks like you can install a compatible version of Colorful Tabs from here: https://addons.mozilla.orgfirefox/addon/_colorfultabs/

            For some of these other features, it’s a bit of a mixed bag. :/ To open bookmarks in a new tab, you can change a setting within Firefox to achieve this. Instructions are here:

            To open a link in a new tab, you can hold down the control button and click if you are on PC, or hold down the command button and click if you are on Mac.

            Unfortunately, I’m not seeing anything for automatically closing bookmarks and history folders, and it doesn’t look like that particular extension will be updated any time soon. 🙁

    1. Roll It Back wrote on :

      You can downgrade back to one the previous/older versions and all your extensions will work again. The quantum update left so many great add-ons incompatible, so I just rolled back to around version 50 until all my favorite addons become compatible with the new quantum. I had years worth speed dial links missing and a bunch of other of my favorite add-ons. All the great extensions is why I have always remained faithful to firefox.

      If you want to rollback just follow these steps.
      1. Visit this link and download the version you want to rollback to ..
      2. Close firefox.
      3. Double click the older version you just downloaded.
      4. Firefox 50 or whatever version you chose will ask you if you want to upgrade.. Click yes..
      5. When your downgraded version launches Click Options > General and disable Automatic Updates.

      Everything should be back to normal. You likely will not even have to reinstall any of your extensions either.

      1. migol wrote on :

        Thanks a lot for your suggestion.

        I downloaded version 56.0.2 (64 bit) (file “Firefox Setup 56.0.2.exe” ) and installed it over version 57.0. The first time I got it wrong because as soon as version 56.0.2 started, it started immediately upgrading to version 57.0, thus I got version 57.0 again.

        Then I went to Options -> General ->Firefox updates and under “Allow Firefox to” changed from “Automatically install updates (recommended)” to “Check for updates but let you choose to install them”. Then I closed Firefox, executed again the installer “Firefox Setup 56.0.2.exe” and then started Firefox again. It stays now on Firefox 56.0.2, but it keeps reminding me to upgrade to 57.0 which is ABSOLUTELY NOT RECOMMENDED AT ALL. Firefox 57 is a DISASTER! Those who managed this upgrade to version 57 are lunatics that will be responsible for the demise of Firefox if the situation with the incompatibility of 80% or more of the extensions is not resolved very, very soon.

        Of course this roll-back is a TEMPORARY solution while I see what happens in the VERY near future. If the disaster remains, then I will have to say BYE-BYE to Firefox (after at least 15 years of faithful usage) and move definitively to Chrome as my default browser.

          Just to put this situation in perspective:

          Ubuntu Linux was the most used desktop Linux version until several years ago Mark Shuttleworth , the big boss of the Ubuntu project decided to introduce the Unity user interface that restricted the usage to menu interfaces and searches in order to start an application, abolishing the prevalent desktop systems with icons placed on the desktop.

          That move was highly criticized at the time but Mark Shuttleworth kept firm on Unity. The result was that Ubuntu lost lots and lots of users and a port of Ubuntu Linux called Linux Mint – which kept the existing Gnome desktop system and did not introduce the Unity system – became the prevalent Linux desktop. Now after so many years of failure, Marc Shuttleworth finally sees the light and drops the Unity system, back to the Gnome system! See

    I’m sorry, but that’s not acceptable. That shows an appalling level lack of consideration for your customers for any user who is not a fully-able adult that your team apparently didn’t give this any thought.

    Fixing this should be a job that is top priority – expecially considering you don’t even give people an option to roll-back – and should the sort of thing that should be hot-fixed in a short space of time (like y’know, days). Or are you really telling us that the new system is SO badly designed that a relatively simple change like UI size is not possible? Because if that is true, it says a great deal about your priorities and none of it good, I’m afraid.

    My grandmother is 90 and see can’t see properly and she had enough difficulty using the interface before (which you’ve now changed around again), and the computer is her lifeline. What is she supposed to do in the “few months” it will take you to fix a basic (or what SHOULD BE a basic issue? (I will have to try to ensure that her version does NOT upgrade.)

    is there any way to recover the old firefox before quantum was pushed? obviously downgrading wont work. thanks mozilla for being update nazis. my productivity went down the toilet, and that is time i cannot get back. besides that, the browser sucks worse than chrome now as far as speed goes. i have the feeling much like youtube and google and other mega corps out there today, mozilla has joined those ranks to force users to like their garbage instead of listening to the users. bad bad bad move.

    No more Add This? How are we now supposed to post and send articles? By copy/pasting everything? This is seriously a game changer. And when I used the find replacement tool all it showed me were ad blockers.

    You just made A copycat version of Chrome ¬¬ Thankas for ruining it. You ruined everything!!!

    So, I had my thesis and doctorate investigation in Zotero wich was a WONDERFUL firefox plugin thta made investigation much less difficult. And suddenly I LOST EVERYTHING I had there (of course I have my backups and all, but now you just can’t use Zotero)! Not because of Zotero’s updates but because of you!

    I had exactly 48 plugins that I was actively using!! Everyone told me to use another explorer because firefox was slow and blah, and I allways said that I needed everything that I have with my complements and I didn’t wnt to and I couldn`t do that even if I wanted.

    You say “For developers of legacy extensions who may be in the process of migrating, or have plans to do so in the future, please note that once your extension is compatible, your users will no longer be prompted to find a replacement, and your current users will automatically get the updated version.” Well, lets see if the users will come back to you after WE change to another explorer because you forced us to.

    So thank you firefox! YOU RUINED EVERYTHING THAT MADE YOU UNIQUE, and ruined a LOT of people’s work with you…. YOU ARE THE WORST.

    How is that this is jus’t NOT VOLUNTARY or whatever..

    And you know what, I won’t apologize for my english cuz gess what!! Autocorrection doesn’t exist anymore or something like that and I just wont be using this shit for anything to google the solution.
    Why I would use a Chrome’s clone??!!

    I just really wish thath Zotero’s team or anyone else would have done some kind of old firefox FORK

    So bye, and not a good one…

    Also extremely pissed off with Quantum – yes, it uses less memory, but my two most used & useful add-ons have gone – FoxClocks & Downthemall .. neither of which have even reasonable replacements.

    They were simple, easily used & extremely well written extensions which were totally squashed by the politics inside the Mozilla world.

    I have also been a faithful Forefox user (& promoter) for many years.

    There should at least have been some help for developers like these, rather than the cavalier ditching of anyone “who disagrees with our approach”. Just like a BIG CORP – like it or lump it!!

    Why cannot I just install whatever I like, anway?? Why would Quantum reject something that you guys refuse to certify?? I know that Foxclocks works with Quantum – you have just decided that it mustn’t …. let me decide, with a warning if you like, but I am the user!!!

    Thanks. I’ve been a user and advocate of Firefox since 1.5,. I included it on a “fix-all” CD I created and sent to less technical end users at 2 different ISPs I worked for. I’ve lived with the changes that inevitably come but this is just a fiasco. My settings are ruined, none of the extensions now work including NoScript. You of course were fully aware of this before releasing but failed to insert a question in the install process so that the user could make an informed choice about having most if not all of the flexibility they’ve enjoyed from Firefox removed. You’re idiots.

    Firefox 57 without Down Them All is completely useless for me. Sorry guys.

    Hi, can I have a replacement for Roomy Toolbar. I think Multi-row toolbar was same, but that too has gone. If no replacement is available for now. I would like to develop a new one. Locations pointing to help and guides will be much appreciated.

  40. Vai0 wrote on :

    Also there is lot of wasted space around toolbar tools. My favorites toolbar used to contain 25 icons earlier in a row. Now it contains only 19 🙁 .

  41. Jordan wrote on :

    No suitable replacements found for any useful extension, Quantum was a really bad upgrade for this reason.

  42. Tony wrote on :

    Wonderful! You’ve managed to make 95% of my extensions, plug-ins and themes unusable. How can I revert to previous Firefox version? If I can’t, you’ve lost a user who has been “in” from the beginning (Netscape Navigator days).

    What a boneheaded move!!! Can no longer download as no and i repeat no downloaders work, despite FF sending me two alternatives, neither of which work either. Who is running this organization, a bunch of girl scouts? This is even unfair to girl scouts, its run by a bunch of stupid clowns. Sorry, but as much as i dislike chrome, thats where im going. Bye

    I’m sure you Firefox people are overwhelmed with all these negative comments, but really, WHAT did any of you EXPECT…??? WHY wouldn’t there be something posted 1-2 weeks before the update, explaining what could happen, and letting people know which Add-Ons wouldn’t be compatible with this new version…?? ALL of the complaints on here are VALID and UNDERSTANDABLE — computers are people’s LIVES!!! Who would think that making massive changes and deletions with how people USE the internet, with NO warning, was a good idea??? Hasn’t anyone paid attention to how Windows is running people off with their constant changes and controls…??
    I LOVE Firefox, but this was/is TERRIBLE Customer Care, and may actually cause it’s END….

    How do I roll back this firefox update so my my extensions will continue to work?
    This has totally ruined the functionality of the browser for me.

    wow thanks for killing all my addons guys

    awesome job

    Are there replacements for



    New Add-on Bar


    SSL Version Control (a Mozilla extension)

    Like everyone else here, now stuck on Firefox ESR 52 – which has stale CA certificates, so is extremely unsafe to use with many banking sites that use newer CA certificates.

    Wow. I’ve been a Firefox user since it was Netscape Navigator. When I switched away from it, I switched to Waterfox. I’ll continue using that as long as I can, but I know that neither it nor Pale Moon will never have enough market share to keep extension developers interested. Now, most of the stuff I use (like Brief, yarip, Menu Wizard, Roomy Bookmarks Toolbar, and about fifty others, on and off) isn’t really necessary, just useful. But…you broke Session Manager, PassIFox, NoScript, and SQLite Manager? And there’s no way to have a status bar? I have to to to the developer window to see headers rather than click Live HTTP Headers? And on, and on…

    Y’know, I hope someone, someday, develops a truly customizable, open-source browser. It would be great to have one.

    I Have been a loyal Firefox user for many years, and trusted it to be better than any other browser out there. I also was extremely happy with the way Firefox could be customized to our/my liking since I am on line for hours every day and customization made it easier and more pleasant to use. But I gotta tell ya, You people really screwed the pooch on this one. I’m all for advancement in technology and improving things to make a product better, but in this case with the upgrade to version 57 of Firefox, you people at Mozilla just alienated and pissed off every single Firefox user around the globe. Stop and think how many users that is…..For me, I was using Classic Theme Restorer and Classic Toolbar Buttons extensions because I did not like the standard UI that Firefox provided, so I customized it to my personal preference. And as far as going to a new page to “Find a compatible replacement”, well….that’s a joke. THERE ARE NO COMPATIBLE REPLACEMENTS! Sure, the extensions I was using are for ease of use and personal preference, but think about all the people that have all their extensions disabled and no replacement exists. I also don’t need an address bar that stretches across almost the entire screen, and I seriously doubt anyone else does either, and I have not found a way to make it smaller. So, yeah, Firefox Quantum….worst piece of crap I have ever seen come out of Mozilla. Of course I am disappointed, yes I am pissed off. I had Firefox set up just the way I like it, and now it’s about as bad as Internet Explorer which I hate with a passion. Thanks a lot for screwing up my favorite browser, Mozilla. What a mindless stupid thing you have done.
