I'm not sure what to do there. did it have a way to enable and disable it before?
I searched for 'mozilla addon no way to enable or disable'
and found
All my extensions disabled with no option to re-enable
in the profile directory, it looks like
extensions DIRECTORY has copies of the addon .xpi's
extensions.json is a file that is the addon's registry
extension-settings.json is the settings of addons
If you want to try to reset the extensions registry by the method listed, backup everything and the profile directory, and see if that helps
Thanks. I’ll keep this handy as a last resort.
