So I'm running 102.2.0 (64-bit) on macos 12.4.

I'm a bit frustrated. Thunderbird always ran well. But reasons unclear it seems like TB at times is

- non responsive, I click and the UI delays and lags after clicks - activity monitor at times shows TB exceeding 100% CPU - system fan starts to blow and looking at activity monitor it shows thunderbird getting 70%+ resources.

what i've done - that haven't worked - if I quit thunderbird the cpu resource frees and fan stops blowing soon afterwards - i have rebuilt the global-messages-db.sqlite and removed .msf files to allow the index to rebuild.
