lately #thunderbird is freezing at start.. very slow response, almost unusable UI. takes a while to get to normal behavior, and sometimes freezes completely (=have to kill process).
using just 14 imap accounts (in 4 different servers) with a few dozen filters, and ~10 RSS feed subscriptions.
also connected to cardav/caldav with a single nextcloud instance.
could be network related, but have noticed same behavior both with slow/fast network connections.
