Re-enable add-ons that were disabled when updating Firefox

Starting in Firefox version 57, only extensions built using WebExtensions APIs will work. Not sure if your add-ons are affected? See Firefox add-on technology is modernizing and these Frequently Asked Questions for details.

When you update Firefox, it automatically checks your add-ons and updates them to compatible versions when possible. If an add-on can't be updated and is no longer compatible, Firefox turns it off. This article shows you how to update those add-ons and get them working again.

Search for updates on the add-on's website

Some add-on makers have different versions of their add-on for different versions of Firefox so updating through the Add-on Manager doesn't work. In this case, an update might be available on the add-on's website.

  1. In the Add-ons Manager tab, find the incompatible add-on on the list. Click on the More link to see more information about that add-on, and then click on the link next to Homepage. You will be taken to the home page for that add-on.
  2. Download the latest version of the add-on from the add-on home page.
Note: If there isn't a version of the add-on available that works, it might help to contact the makers of the add-on while you are on their website.

Search for alternatives

There may be other add-ons with similar features that are compatible with your version of Firefox. The Add-ons site is a good place to find alternatives.
