This problem began slowly for me; sometimes Thunderbird wouldn't restore/show, but I could kill it and start it again and all would be fine.
Now it's stopped starting for me entirely. I tried moving my .mozilla- thunderbird directory and starting it with -safe-mode to no avail. I'll still see it giving me little messages about it downloading mail, but won't show itself. Weirdly, it will also show dialogs warning me about things like expired SSL, but alas, still no dice in actually bringing up the main window. I'm at my wits end! I get up this morning and I can't read my email. -- [Intrepid] Thunderbird's main window is invisible https://bugs.launchpad.net/bugs/328608 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
