Thunderbird freezes for several minutes every time an operation is done while Inbox is open
Hi all,
I've been using Thunderbird for eons but yesterday morning it started freezing up constantly.
It freezes up ("Thunderbird is not responding") every time new emails are received or any time I take any action while the Inbox folder is open. So, if I delete an email it freezes for a few minutes. If I do anything pretty much, it freezes up for a few minutes. Then it comes back and I can do another action, and it freezes again. This only seems to be happening when I have the Inbox open - if I go to other folders it seems to function normally.
Things I've tried without success: - Troubleshooting mode - Adding exceptions for my profile folders to Windows Defender - Compressing Inbox (and Trash and Junk) - Repairing the Inbox index
This doesn't appear to be a memory issue - right now, memory use for my entire system seems to be hovering at just over 50%. But Thunderbird is still freezing.
My Inbox folder is very large, but it's never been an issue before and nothing significant was added yesterday when it started failing.
Any suggestions appreciated!
Thanks

I’m having the same problem on two computers. Thunderbird freezes a few seconds after launching. Restarting the computer doesn’t help; launching it in Troubleshoot mode freezes just the same – there’s nothing I can do. This has been happening for about 2–3 days.
Even though creating an exclusion for the Thunderbird profile folder should eliminate Defender from the list of potential culprits, you may still want to start Windows 11 in safe mode with networking enabled.
Does the problem go away?
Windows safe mode disables anti-virus software. This is a troubleshooting step, not a solution.
Note, Windows safe also disables WiFi. So you'd need a wired LAN connection for Windows safe mode.
Well, that's odd - I swear I had tried this at the start of my troubleshooting, but I did it just now and it worked! In safe mode, Thunderbird works normally. Thanks for the prompt!
So now what? I don't have any third-party antivirus running, just the native Win 11 defense.
Thanks for the lead!
Is there any other forgotten anti-virus/security software running on your computer? If you do have multiple profile folders, make sure the one you picked for the exclusion is the one you're having problems with.
Beyond that, https://wiki.mozilla.org/Thunderbird:Testing:Memory_Usage_Problems has a comprehensive list of troubleshooting steps.

No, no other security software running. And certainly nothing had changed the other morning when this all stopped working; this setup had been running fine for years.
