It's hard to pin down when exactly it will happen but Thunderbird regularly freezes from roughly 10~15 seconds after clicking the red close button. In that time TB doesn't allow the desktop or any other app to become active until it finishes whatever it's doing. The bug occurs after I've brought it to the front and then close it. For example, an email just arrived so I checked that then closed TB. That's when it hung.

I've found it also happens after discarding a draft so that I'm unable to open or even highlight other emails in my Inbox for a short time. This hanging started happening right after I upgraded to Mac OS X 26.2 a few weeks ago. So far I've tried...

1) Troubleshoot Mode. No change. Even with no extensions or themes installed the problem shows up. 2) Increased the value of mail.db.idle_limit 10X to 3000000. 3) Did a clean reinstall of the app (v146.0.1). I redid Settings from scratch and imported emails from a previous installation. The size of the Profiles folder is 991MB. 4) no anti-virus software is installed.

It's similar to this bug. I made a comment there 2-3 weeks ago but no reply so far. https://bugzilla.mozilla.org/show_bug.cgi?id=1998881

Also similar to this... But I don't have a calendar installed. https://bugzilla.mozilla.org/show_bug.cgi?id=2000460

Not sure what else to try. Any suggestions?

Hello,

I have a MacBook Air M2, and I'm experiencing energy usage issues related to Thunderbird. This has kept happening for a long time now actually, surviving through at least two Mac OS updates, and a huge number of TB updates. Everything's up to date. I tried to follow this: https://support.mozilla.org/en-US/questions/1269944 and this: https://wiki.mozilla.org/Thunderbird:Testing:Memory_Usage_Problems?_gl=1*86dj4d*_ga*MTkzNzQ0MjA3MS4xNzYyOTY4OTMx*_ga_2VC139B3XV*czE3NjMzMTM3NDckbzIkZzAkdDE3NjMzMTM3NDckajYwJGwwJGgw but didn't succeed. Actually, in my case, the issue is more noticeable: I normally have TB open in background - sometimes everything's fine, and the battery goes down as normal, while sometimes instead the battery drops quickly, and checking in the Mac activity monitor I can see that the CPU usage of TB is totally abnormal. When this happens, I can actually see the activity bar in TB being live (bottom right corner, as it happens when TB is checking for new mails), but never disappearing. When I notice it, I just reboot TB, and the bar shuts off as normal after a quick mail check. Moreover, checking the 24hr energy usage by app, TB is often on top with nonsense values.

I tried multiple times to rebuild the database, and do most of the tricks suggested, but didn't fix. Yes I have a huge mail archive, but the problem is not the standard management of this database: basically it seems that every now and then, TB decides to run some activity which it gets stuck in, and this kills the CPU.

Thank you in advance for your help!
