User Agent: Mozilla/5.0 (X11; Fedora; Linux x86_64; rv:94.0) Gecko/20100101 Firefox/94.0
Steps to reproduce:
Open thunderbird. Setup 2 imap accounts (~10K messages in inbox and folders) and lightning with ~20 ics calendars on 30minute refresh.
Actual results:
CPU usage however at 100% (1 core) permanently. Actually it has been like this for many months. I have however added a profiling: https://share.firefox.dev/3bDswTy which perhaps helps someone understand this.
Expected results:
Some idle state, battery not drained.

Do you have a lang pack installed? Tried Help | Troubleshoot mode?

Hi Magnus,
Thanks for the response. I don't know what you are driving at with langpacks, but here are the rpms:
langpacks-core-font-en-3.0-15.fc35.noarch
gawk-all-langpacks-5.1.0-4.fc35.x86_64
glibc-all-langpacks-2.34-7.fc35.x86_64
glibc-langpack-en-2.34-7.fc35.x86_64
langpacks-core-en-3.0-15.fc35.noarch
langpacks-core-en_GB-3.0-15.fc35.noarch
libreoffice-langpack-en-7.2.2.2-1.fc35.x86_64
langpacks-en-3.0-15.fc35.noarch
evolution-data-server-langpacks-3.42.0-1.fc35.noarch
evolution-langpacks-3.42.0-1.fc35.noarch
evolution-ews-langpacks-3.42.0-1.fc35.noarch
langpacks-en_GB-3.0-15.fc35.noarch
troubleshoot mode I was also unaware of. Awesome! It cures the problem! So this means I should be looking at my add-ons? I have Mail merge, mailbox alert, provider for exchange activesync, provider for google calendar, & tbsync. But when I restart thunderbird in normal mode...the CPU burn is gone!!!! So it seems a quick trip into troubleshoot and back out has cured a long-standing issue. While this is great I cannot help feeling that a reproducible issue would be easier to eliminate...
But thanks!!!

I think magnus has nailed it. THere is currently a problem with language packs. You might disable them until the problem is solved

Hi Magnus,
Thanks...if the CPU usage climbs again I'll try. A quick google seemed to suggest I need to remove the rpms, there is no disable in thunderbird?

The official thunderbird builds do not ship any language packs, and installed lang-packs can then be disabled like normal add-ons.
But for distro-installed ones I don't know...

Hi Magnus,
After leaving the computer overnight the power usage of thunderbird climbed up to 100% again. So I tried removing the rpms langpacks-core-en_GB-3.0-15.fc35.noarch langpacks-en_GB-3.0-15.fc35.noarch and cycling thunderbird through troubleshoot mode again. This fixed things for a couple of hours, but now I am back to 100% CPU usage. I am reluctant to delete the langpacks-en-3.0-15.fc35.noarch - would that mean I had no languages?
This does not feel to me like a duplicate of 1728744 - startup is fast.
Does the profiling not provide any clues? The time is going in "pulltimelinedata" - is that part of lightning?
