Thunderbird Freezing ("Not Responding") Repeatedly
I'm experiencing a recurring issue with Thunderbird. After running for a few minutes, it freezes and displays "Not Responding." The only way to fix it is to close the program and restart it, but the issue happens again after a short while.
Here’s what I’ve tried so far:
Updated to the latest version. Tested in Safe Mode (issue persists). Disabled antivirus (Bitdefender) to rule out interference. Cleared startup cache. Reinstalled Thunderbird and restored profiles manually.
Reinstalling solved the issue temporarily, and Thunderbird stopped freezing. However, the problem returned after I imported all my email accounts!!!
I’d appreciate any guidance on how to resolve this!
Thanks in advance!

Create an exception in Bitdefender for the Thunderbird profile folder, so that the BD real-time scanner will not scan it. https://support.mozilla.org/en-US/kb/profiles-where-thunderbird-stores-user-data#w_how-to-find-your-profile
I have already disabled bitdefender and added profile folder to exception. That didn't help.
Which is the size of your biggest account folders in the ImapMail and/or Mail folders in the Thunderbird profile?The fact that reimporting your email accounts provokes freezing of TB shows that there are to many messages or corruption in one or more of the mbox files. I am following a similar freezing problem in the German Thunderbird forum with a profile containing 192.000 files (mostly *.mozmsgs files) and 20 GB.
