I try to enable or disable extensions in Firefox. It says "Restart Firefox to complete your changes". I press the restart button and it restarts. When it comes back up, the extension is unchanged. How do I fix this?
This isn't just one specific Add-on. I've tried disabling lots of add-ons at once. Some of them lose their icons and stop working, for one session, but they are still shown, with a "Disable" button, in Add-ons, and they come back fully when I restart Firefox.
If I go into safe mode, tell it to disable all extensions, and then disable them all manually, their functionality no longer exists, but the Add-ons still shows them with "Disable" buttons, but with many missing icons:
If I then disable an extension and restart, all the ones I disabled are back to normal enabled again.
