All,
As part of https://bugzilla.mozilla.org/show_bug.cgi?id=1772023 I tested with Thunderbird 102 Beta. There are a number of changes between 91 and 102 (for the good, new address book format -- no more Mork!, etc.) that will make irreversible changes to your thunderbird profile.
If you are considering "checking out" a new version of tbird, make a backup of your current profile before trying the new version (thunderbird wisely creates a new profile, but for testing CPU use, I needed to use the same account setup).
The downside of the new profile creation is if you have a number of mail and calendar accounts to integrate, creating a new profile from scratch will be tedious and the sync of all mail headers, indexing, etc.. can be extensive if you have a large mail-store. So after backup, you can point thunderbird to your existing profile with the '-profile /path/to/your/profile' option and it will use and convert your existing profile to the new format. (but without a back, you will be unable to use the old version of thunderbird with that profile)
The good new is High CPU use is gone in 102 beta...
I had several misgivings with Thunderbird v91, the high CPU load being certainly the weightiest amongst them. I don't recall all the issues but just to note one or two others: Opening additional TB windows (most notably composing a new mail) causes visual artefacts with parts of the window missing. I have to click out and back in to display it properly. FF has also had visual issues when launching in full screen mode for the last several months, maybe it's related. I have Intel 915 graphics. Also new items in the Folders / Feeds pane no longer show a preview on hover. A small thing but something I found useful particularly with my feeds. I could get a glimpse of what new feed items I have without the folder losing its blue highlighted 'new content' status. Have you witnessed either of these under v102? gumb
