Sometimes when upgrading or testing beta versions of Mozilla Firefox, add-on developers may not always have their add-ons ready for the latest and greatest version of Firefox. I’ve run into this a few times, and if it is a favorite add-on that you don’t want to part with – here are some great solutions!
Solution #1: Uninstall/Reinstall
From the Mozilla Firefox Add-ons Manager (Firefox menu> tools > add-ons), locate the add-on that you want to uninstall and click on remove. Reinstall the add-on from the Firefox add-on repository or from the developer website.
Solution #2: Add-on Manager
Since Firefox automatically turns off the add-ons that can’t be made automatically compatible - you can still get most add-ons working again after a browser upgrade. Mozilla support recommends that you re-enable add-ons that were disabled when updating Firefox by:
1: Check for new versions from the Add-ons Manager and click on check for updates.
2: If updating through the Update Manager fails, you can search for updates at the developer website. From the Add-on Manager tab – click on More, this will give you a link to the add-on homepage.
Solution #3: If all else fails…
Download and install Disable Add-on Compatibility Checks. From the Add-ons Manager enable Add-on compatibility checking (at top of the page); with this add-on you have the ability to enable any add-on that is incompatible.
