@Anders: Thanks, and thanks for your helpful input! Disabling transparent menus did seem to help, in that I was able to work intently for about 2 hours w/o menus disappearing. This is a much longer period than I've experienced in recent times (menus typically disappear on me every several minutes; hence, my aggressiveness in trying to help "working the problem" :) ). I'm not sure this tells us much, but it seemed worth mentioning, and I promised to report back.
Sigh. I'm beginning to run out of ideas, short of compiling debug versions of compiz and firefox, and I just don't know if I'm for that anytime soon. :) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/872207 Title: When Firefox is running in Unity, drop-down menus sometime close when opened To manage notifications about this bug go to: https://bugs.launchpad.net/compiz/+bug/872207/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
