What security software do you have?

It is possible that security software (anti-virus, firewall) is causing problems. Try to disable security software temporarily to see if that makes a difference.

Can you download and save the xpi file to your desktop?

If that works then try to drag the file in a Firefox window.

Tried all of that, didn't work.

Can you install an extension if you start Firefox in Safe Mode?

Try to start Firefox in Safe Mode by holding down the Shift (Mac: Options) key to see if that has effect.

It is possible that there is a problem with files in the profile folder that store the extensions registry.

Delete the extensions.* files (e.g. extensions.json, extensions.ini, extensions.sqlite) 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 "3-bar Menu button/Tools > Add-ons > Extensions" then click the Tools button at the left end of the Search bar to check if there is a compatibility update available.

If this didn't help then delete Add-ons.json and possibly prefs.js in case there is a problem with preferences.

You can use this button to go to the current Firefox profile folder:


Create a new profile as a test to check if your current profile is causing the problem.

See "Creating a profile":

If the new profile works then you can transfer files from a previously used profile to the new profile, but be cautious not to copy corrupted files to avoid carrying over problems.
