Secure Connection Failed is blocking all sites including Mozilla Support

After restarting my mac, I receive a Secure Connection Failed error for all sites including Mozilla. Safari works without a problem but Firefox is completely blocked. Besides restarting, I did not make any changes (unless a new version of Firefox auto installed). Running 107.0.1 on a mac with OS 12.6

The problem has resolved itself - I waited 10 minutes and tried Firefox again and it is working normally again.
