Thunderbird hits 100% CPU usage [inexplicably solved]
I noticed Thunderbird hitting and maintaining 100% CPU usage recently. On Toad-Hall's advice, I tried to narrow down to a particular add-on. In this case, disabling the Provider for Google Calendar add-on appeared to stop the behavior, but re-enabling the same add-on did not cause the behavior to return, so it's not clear to me whether Provider for Google Calendar was actually causing the problem. At any rate, it's not doing it now. Maybe this'll be useful to someone else.

re :Thunderbird freezes or is extremely slow
You should have asked your own question. You do not have the same symptoms - when you go into Safe Mode, it resolves your issue. The person in other question has issue regardless.
Standard practise when Thunderbird safe mode works is to disable one addon, restart Thunderbird and test performance. Repeat this until you locate the addon causing the issue.

Hi, I'm having a similar problem, which seems to have started recently. My machine has 4 cores, and tbird eats up 100% of one shortly after being launched, but the UI remains responsive. For me, Safe Mode does make the problem go away, but of course I want my add-ons to be functional. Using the same log setup as MarcoZ62, the log stops dead in the middle of a line like his does. Here's my Troubleshooting Info (with account stuff redacted):

Let me know what else I can do to gather information and generally help solve this! Thanks!
Apologies then. I didn’t want to create a duplicate if it was the same, but I see my error in judgment. Let me see if I can fix this question, or if not I’ll start a new proper one.
