Thunderbird has been my mailer for more than 15 years. The latest incarnation Supernova is awfully buggy. I installed version 102.3.3 in early October and since then had lots of grief. Updating to 115.3.2 on Oct 13 and to 115.3.3 today did nothing to improve things. The program suffers lots of freezes and is just not functioning well. I tried to file this report from within T-bird following Settings -> General -> Release notes (under Updates) -> file a bug in Bugzilla and ended up with an empty, unresponsive page (see attached). There appears to be something very fundamental that needs to be fixed.
