I am unable to install extensions, they show up with "will be installed after you restart Firefox" even after I restart.

Hi,

I am unable to install extensions, they show up with "will be installed after you restart Firefox" even after I restart.

The "Staged" folder is present and remains after a restart, but the extensions do not get installed. They show in the extensions page with the "will be installed after you restart Firefox" message and remain like this no matter how many times I restart.

Any Idea's?

Running Firefox 24.0 on Windows 8.1

Many Thanks, BD

P.S. Just tried to install the "troubleshooter" add-on before posting the question and I got an error saying it cannot install because it cannot modify the needed file. (I did it manually instead)

I already tried deleting the extensions.* files to no avail. However i deleted the addons.sqlite file and restarted my computer (actual computer not just Firefox) and that seemed to do the trick. Problem solved.

Thank you for your assistance, it is appreciated.

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.
