Folks, I’m seeing a lot of people recommend setting xpinstall.signatures.required to false to fix the Firefox extensions issue.
⚠️ DO NOT DO THIS! ⚠️
It disables signature checking on extensions which means that you open yourself up to malicious extensions if you install any new ones or if you have auto updates on.
Or go the officially recommended (but less private) route: https://mastodon.ar.al/@aral/102039553570119536
