Almost all of my customers @FeilnerIT are reporting / asking / needing a fallback now. "What if Trump..." alternatives is a bestseller. And there's thousands of accounts at big entities that are currently recieving "backup" systems like opendesk or @grommunio with which they can work even if #POTUS does foolish things again. Or more criminal ones.

Works fine here both on #Fedora 43 and #SUSE #Opensuse #Tumbleweed. But you will need Thunderbird 146. (Fedora brings that, opensuse needs #opi installation from #Mozilla repos).
In this video you see how I delete an older account and remove the Exquilla plugin before successful install (noaudio)
