I expect you might be seeing disabled Legacy add-ons, or see that some of your add-ons were disabled after you updated to Firefox version 57. In Firefox 57, The WebExtensions API enables add-ons to be more secure and perform better with your browser. For more information, see Firefox add-on technology is modernizing.
Unfortunately not all add-ons were updated to this new standard. Mozilla created a feature to help you find a replacement for your favorite add-on. Read more here.
To find replacements for your legacy add-on:
- Click the menu button
and choose Add-ons (or enter about:addons in a new tab).
- In the Add-ons Manager that opens, Click Legacy Extensions
- Click the Find a Replacement button next to your legacy add-on.
If a replacement doesn’t exist or isn’t helpful, please use this utility to find recommended alternatives. If you don’t find a suitable replacement, please head over to the add-ons forum for help. We expect legacy add-ons to continue migrating to the new WebExtensions standard, even if they missed the Firefox 57 release date.
There’s also a community-sourced list of alternatives on Google Docs.
Due to other changes in Firefox, Mozilla could not delay the switch to WebExtensions APIs. Mozilla Support volunteers are here to help you find alternatives to your favorite extensions. To start, use this utility to find recommended alternatives. If not, please head over to our forum to ask for help.
