The problem seems to be NOT firefox itself because I have a separate firefox installation which works in Breedy without any problems but causes the same output started in Dapper Drake.
IMHO the problem must be caused by GTK or the x environment -- firefox doesn't run properly and crashes badly https://launchpad.net/bugs/46547 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
