Firefox 127 contained a certificate that expired on Friday, March 14. That certificate was used to verify the digital signatures on extensions. Now, none of them can be validated in older versions of Firefox.

Can you update to Firefox 128? See: Update Firefox to prevent add-ons issues from root certificate expiration.
