Topic: My ignorance! Working side by side with my bank account 1/2 size, and 2 columns of my inbox screen 1/2 size worked great! A job well done! Re-sizing TB screen back to normal size caused a large blank screen, headed "Inbox", with only a couple of blank columns, no folders, no Sent, no Trash, and it is unresponsive. I went out and back in and it is the same. I didn't do anything unusual. This is a fairly routine action. Please can you help?

Other than being slow to download my emails now for a few months, TB was performing well until a week or so ago. Now it also won't open the downloaded email when I click on it and the TB freezes up so I can't close it out. I have tried restarting computer multiple times and it works for one or two emails that I can open and then starts freezing up again. Makes using it almost impossible. I have security Windows 11 Defender only and have had it the entire time when it also worked well.

Hello, It's been a few days Thunderbird freezes when I want to save a message on the computer (save as). When I close the saving window which is not responding, it automatically saves the message on my desktop. The file where the last message was successfully saved is still existing so I don't think it is a path problem. I have tried to restart it without the add-on but it doesn't change anything. And it is up-to-date. Anyone knows what the problem could be? Thank you! Estelle

On Sunday, May 7, my Thunderbird program suddenly stopped responding (neither the shortcut nor the program itself will run); clicking on the shortcut icon or attempting to open or run the program itself causes the "loading" or spinning wheel icon to pop up, run for about 10 seconds, then stop.

I've used Thunderbird as an email client for my Sonic email account on my pc for over 8 years without any difficulties until now, and now seem to be locked out of my Thunderbird account. I cannot access it to confirm the version, although I believe it is current, since it appears to update automatically.

My Sonic account continues to function normally, but I keep (save) all incoming and outgoing emails in my Thunderbird system and now am unable to access any of those, and unable to access my Thunderbird account at all..

I've consulted with Sonic over this; Sonic maintains that any difficulty must be on my end connecting to Thunderbird, and suggested that I might have changed the account password. However, I have not changed the password, etc.

Please help asap.

Thanks, immensely.

This is Ellen. I tried restarting Robert's ( my late husband) computer after it crashed and I got the message about Thunderbird's inbox folder not being able to be opened because it is in use by some other operation. It is an old Mac Mini running 10.13 and it says TB is 115.18.0. I don't update it because I don't think his OS can handle anything newer. I just looked and my Mini with an M1 chip (4 y/o?) is running 140. something.

How do I get it to quit whatever it is hung up on? His email is coming in ok on my iPhone.

Robert was a sculptor who made large kinetic works and a lot of his work is still on this computer.

Please help me get out of this mess. I think it has happened before.
