What's the Firefox version number?

Following on to the last reply, you need at least version 115.13.0esr from July 9, 2024, to use any extensions. See: Update Firefox to prevent add-ons issues from root certificate expiration.

There could still be individual extension issues, so in that case, you could mention the problem extension.
