I last saw this recently, though I still can't reproduce it at will. It happens in both GNOME and Xfce.
Recently I also had another bug: the "You are about to view an encrypted page that contains some unencrypted information" alert sometimes appeared on https://webmail.ox.ac.uk, which hadn't triggered such a warning before and according to its technical support shouldn't. This may be a duplicate of https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/60236; I have not tried any of their suggested workarounds. I will try -safe-mode next time I see the bug. -- Randomly crashing (SIGSEGV/SIGPIPE) https://bugs.launchpad.net/bugs/78809 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
