Every time I open Thunderbird on Ubuntu Lucid it opens as a tiny window (maybe 2px wide by 15px high) in the top left corner of my desktop. When I expand the window it's just blank. The behavior started after I restarted the application because every time I sent and email it would open that same blank little window.

I fixed this once by opening the profile manager ($thunderbird -ProfileManager) and recreating my profile.

Does anybody know what could be causing this? I can't really find anybody else with this issue on Google.


I had this issue before and the reason was that some other process (or more likely myself by accident using sudo :) had been messing with the file-rights of my profile- / mailbox-files. It seemed that just starting Thunderbird with root-rights can cause this.
Thunderbird couldn't read any information from the profile and behaved the way you described. Don't ask me why ...

The fix was to chown and chmod the profile-dir recursively.

    Somehow another rogue thunderbird process started. Killall and a restart fixed everything, but I'm going to take your advice so hopefully it stops happening. Do you suggest chmod 700? – PMV Oct 22 '10 at 15:44
