Add-on Compatibility for Firefox 52

9 responses

If you haven’t read it yet, please give our plans for 2017 a look. These updates are aimed mostly at add-ons using legacy APIs, but WebExtensions is the way forward.

Firefox 52 will be released on March 7th. Here’s the list of changes that went into this version that can affect add-on compatibility. There is more information available in Firefox 52 for Developers, so you should also give it a look.

General

XPCOM and Modules

Themes

Let me know in the comments if there’s anything missing or incorrect on these lists. If your add-on breaks on Firefox 52, I’d like to know.

The automatic compatibility validation and upgrade for add-ons on AMO will happen in a few weeks, so keep an eye on your email if you have an add-on listed on our site with its compatibility set to Firefox 51.

    Looks like I’ll be switching to Pale Moon in 2017, then. (Take a look at the comments section of the “plans for 2017” article to read many, many reasons). I am not convinced many of the add-ons I use can or will be converted to the new system, and without these add-ons, there is no reason for me to stick to Firefox any more.

    With your latest update you seem to have broken privacy Badger with a skin that shrinks it right down in the block list and stops me blocking tracking domains by reseting itself back to unblocked on sites I block .I also cant scroll down as it blocks me , it looks and acts like a virus– 122d-fd53-4335-8bf4-053289/skin/options. I want it back to what it was , but it looks like a hidden file in Linux. Dont use Firefox much now as it looks like Firefox is wanting me tracked.

      Have you contacted the developers of Privacy Badger about this?

    Great post on Firefox 52. I like the extensions and security, as well as privacy built into the browser. Thank you for your efforts, Darren Chaker

    I’ve used Firefox for many years and use add-ons a lot. I’m not a programmer and have no idea how to write one.

    I’ve spent the last 30 minutes trying to find some way to send a message to someone in the developer network and this is the first chance I found. So, you’re it.

    I have a request for an add-on. I just spent the last several hours revisiting all my bookmarks to restore the favicons. They were lost when I had to reinstall Firefox. I’ve looked but can’t find anything for this. I would love a simple add-on that would backup favicons for later retrieval. I suppose it would be on par with a way to add favicons from a separate set of icons from other sources. I currently use IdentFavicon for those sites that don’t have one.

    Hope you can pass this on to someone interested in doing it.

    Thanks,
    Dr. Ken Rich
