How can I stop Firefox asking to install things from its extension folder every time it starts up?

Publié

This happens with both versions of Firefox 3.6.28 and 22. (I have removed the latest version because I had so much trouble with it and no, I don't want it back and I am fully aware of the dangers the old versions put me in, thank you!) I have tried to delete the things from the extension folder, but the items it is asking to install aren't in there. I am using XP with SP3.

This can happen if you use the same profile folder with different Firefox versions (i.e. the version listed in compatibility.ini is different).
You should always use separate profiles for each Firefox version.


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

Delete the extensions.* files (e.g. extensions.sqlite, extensions.ini) 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 or not compatible extensions in "Firefox/Tools > Add-ons > Extensions" then click the Tools button at the left end side of the Search Bar to check if there is a compatibility update available.

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