After being forced to create a secure password for what is an account I don't give a rats ass about the security of and now dealing with this ridiculous fiasco, I'm reconsidering whether Firefox is the browser for me. If I don't get a response that quickly restores my extensions, I think I'll just stop using Firefox.

Did you reset Firefox?

If you reset Firefox then a new profile is created and some of your data (bookmarks,history, cookies, passwords, form data) is automatically imported and your current profile will be moved to the desktop (Old Firefox Data).


It is possible that there is a problem with the file(s) that store the extensions registry.

Delete the files extensions.* (e.g. extensions.sqlite, extensions.ini, extensions.cache) and compatibility.ini in the Firefox profile folder to reset the extensions registry.

New files will be created when required.

See "Corrupt extension files":

If you see disabled, not compatible, extensions in "Tools > Add-ons > Extensions" then click the Tools button at the left side of the Search Bar (or click the "Find Updates" button in older Firefox versions) to check if there is a compatibility update available.

If this hasn't helped then also try to delete the addons.sqlite file.
