HOST: Raspberry Pi 4B (8GB) OS: Debian 12 (Bookworm) LM: Slim (1.3.9) DE: None WM: JWM (2.4.3)

As part of yesterday's daily update, apt-get installed thunderbird-102.5.0 in place of thunderbird-102.4.1 -- the result? top -d1 displayed a constant 100%-200% CPU use (with system loads of 4-5+), during the startup and throughout its presence on my desktop. Loading messages took several minutes (I keep my Inbox small, preferring to sort messages -- automatically or manually -- into subfolders); populating the calendar took almost seven minutes -- neither is acceptable.

In the end, I removed v102.5.0 and replaced it with v102.4.1 -- I hope this issue is not particular to my setup, and that it will be remedied sooner, rather than later.

It is worth noting that users have previously reported issues with Raspberry Pi, and we do no testing on this platform.

I'm not aware of any Thunderbird patches that might cause this problem in 102.5.0 - the list of patches is https://bugzilla.mozilla.org/buglist.cgi?bug_id=1796964%2C1782646%2C1795751%2C1798161%2C1795605%2C1794997%2C1795578%2C1797927%2C1795547%2C1794775%2C1792281%2C1795709%2C1787531%2C1798701%2C1792923&list_id=16296395

And I think it unlikely that the gecko side of the code (from Firefox) would have introduced such a problem.

A performance profile might help pinpoint the cause https://support.mozilla.org/en-US/kb/profiling-thunderbird-performance
