Thunderbird is hung up sorting 9000 emails. I downloaded and upgraded program, turned off my computer. I can't get it to stop sorting. Its been hours.

All the tabs, in both my profiles are constantly crashing. I cannot keep at a task for more than a few minutes without needing to restart the tab. Is this a setting problem? I've cleared the cache, and reset Firefox, to no avail. Thank you for any relevant advice and/or assistance.

Suddenly Thunderbird takes a long time to download even a few (10-20) emails from Gmail and then it freezes on an email and as I click on different emails only the original one shows on the bottom half of the screen, even if I change to a different folder/email account. Also it will not close when I hit the X in the upper right corner.
If I click on one of the other apps, such as Calendar it goes to calendar but when I go back to email it still shows that same frozen email.
I tried clicking on the three bars (hamburger) to find the Thunderbird version and nothing happens.
I have restarted the computer but that has not helped.
This is an add on to the previous portion that I wrote yesterday. Today nothing shows in the portion where I usually view the message after I've clicked on it. Also the options in the tool bar such as File, Edit, View etc. do not respond to a click after the first time I have attempted to look at a message.
I am considering uninstalling and reinstalling. If I do that will it find all my emails and folders etc. again? There are a few emails that I am quite desperate to access that I have put in folders.
I'd really appreciate any help I can get on this as some important work is being delayed until I can access those emails.
Thanks for any assistance!

Good morning
Since this morning (05/03/2026) Thunderbird freezes within a minute or two of opening the program.
Everything in the program freezes up. I cannot even close it.
I am running Version 140.8.0esr on a Windows 10 PC.
Initially I was getting a pop up warning message that ask me to confirm if I wanted to send an email with attachments of over 20 MB. There were 3 or 4 such messages. I had not tried to send such emails.
I checked the Outbox in Local folders for old messages, but it was empty. I also checked the Unsent messages files in Local Folders in the Profile folder. I deleted the Unsent Messages.msf file to no effect. I renamed and replaced the Unsent messages file. Also no change.
I checked for crash logs but there are none.
I have run out of ideas as to what to try next. Does anyone have any advice?

I use Linux Mint and I have been experiencing numerous system crashes involving Firefox which requires a cold boot. What is the problem? How can I debug this? Are you getting crash reports?’
This happens several times a week. It has happened continuously tonight since installing the latest update via the Software Manager.
The program causes a total freeze of the OS. All other running programs and all input sources. I have no choice but to shut down via the power button on the tower.
Mint generates crash reports but I have no way to determine if they are being sent to Mozilla.
Firefox for Linux does not provide a troubleshooting system like it does on Windows. Neither does Mint.
I studied Computer Science in the 80s when Firefox was known as Navigator. I learned C and the Unix OS, but since then I became a psychologist, and don't remember too much of the Com Sci stuff I learned and I don't think Mint allows user modifications anyway.
What can be done to fix this? I don't have the Benjamins to buy a new Windows to replace the Linux, nor do I want to.

I have asked several times, and received no responses that helped. I am continuously hammered with GAH! I've tried everything I've found both from Mozilla, and Google AI, but have had no solutions. What am I missing? If I have to uninstall, then reinstall Firefox, I'm going back to one of the better versions, like 98, or 99, or earlier, which I've got on old HDD's that still function. Thanks to anybody who can offer a real solution.

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.

I am running Windows 11 Pro 25H2. After updating Thunderbird recently to the latest version, it is crashing immediately upon starting Thunderbird, not even bringing up the initial screen.
The message is
"Thunderbird has stopped working. A problem caused the program to stop working correctly. Please close the program."
In addition, it brings up the Mozilla Crash Reporter, which states
"We are sorry
Thunderbird had a problem and crashed. We will try to restore your tabs and windows when it restarts."
I do not want to lose all my old POP3 messages, etc.
Please help, Nina
I cannot open my email on to the thunderbird desktop app
