Not all facilities of the extension. They get stuck at < nom_extension > ' will be installed after Firefox restarts." Restarting Firefox does not change this

I've always been able to install extensions with no problems until a few days ago. Since then, the extension installation process gets stuck to where they appear in the list of extensions (topic: addons) with the message < name > "will be installed after you restart Firefox." Restart of Firefox has no effect on this point - after that restart, the extension still says "will be installed after Firefox restarts." I tried several restarts Firefox and I tried to install other extensions, and the same thing happens with all I'm trying to install the extension.

I know I'm running an outdated version of Firefox, but please ignore this. I have a good reason for it.

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

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

New files will be created if necessary.

See "extension corrupted files:

If you see disabled extensions or is not compatible in ' Firefox/tools > Modules > Extensions ' and then click the Tools button at the left end of the search bar to check if there is an update available compatibility.

If this did not help, then also delete the files addons.json and addons.sqlite possible.

You can check for problems with preferences.

Delete a possible user.js file and files numbered prefs-# .js and rename (or delete) the file prefs.js to reset all the prefs by default, including the prefs set via user.js and pref which is no longer supported in the current version of Firefox.
