Olivier, since I wrote comment #26, I actually got it working and since then it seems to be reliable. What I did was:
1. Stopped Thunderbird, which had been running in safe mode. 2. sudo apt remove thunderbird-locale* 3. sudo apt install thunderbird-locale-en-gb 4. Start Thunderbird normally. I've since stopped and started it about 5 times normally, and all seems to work correctly. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1901829 Title: thunderbird fails to open, xml parse error To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/thunderbird/+bug/1901829/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
