Created attachment 841609 [details] Screenshot of thunderbird-78.2.2.tar.bz2 (In reply to Wolfgang Rosenauer from comment #6) > Is anyone open to try the corresponding upstream build for 78.2.2? > > I'm really wondering if the whole issue is upstream or also in our package: > http://ftp.mozilla.org/pub/thunderbird/candidates/78.2.2-candidates/build1/ > linux-x86_64/en-US/thunderbird-78.2.2.tar.bz2 OK... Apologies for the delay :) Yes, that seems to work OK. Set up a very minimal version with all TB defaults and only one mail account and all looks good. Don't think I'd want to see a release candidate in the repositories though...
