Is anybody else having a problem where Thunderbird often uses 90% or more of the CPU? I’d ask if it was a Mac-specific issue, but I ran into a similar problem on Debian.

Is it possible that this is a common problem and I’m just the only one who likes to leave email clients open instead of opening, going through my email and closing the email client?

p.s.
Do you have to run a Mastodon server just to be able to use the Mastodon social network?
