Hi, Been a Thunderbird user for many years - decades. Suddenly, this morning it won't load or open. Tried repeatedly, always same error message. Running Mac Sequoia 15..1.1 Get a crash report, then attempt to reopen but always same result. Screengrab of how it looks attached, this is just before it crashes. All current e-mails inaccessible, and most of the archive stretching back a long time.I've been able to set up MacMail on the active accounts so I can now receive and send, I have managed to import some old archive but everything for some years, particularly recent archived is inaccessible. There have been a couple of instances over the past week where loading was slow, opened to a blank window but a quick restart always worked. Not this morning. How can I continue? Or at least open to access archives. For some reason tre archive folder structure changed some years back and I can't access those more recent folders.

Please advise.......

Dear Sir We had recently installed fire fox, trying to import outlook data for same POP account with same password, but firefox showing importing data folders also created, but no progress seems. can you suggest some solutions.

thanking you

After an update of TB and extensive cleanup, I still cannot move some but not all incoming messages to local folders.

This problem has existed for a long time.

I have purged all .msf files to no avail.
