OK, after uninstalling flashblock I had two pain-free days with no blank windows.
Today I got tired of all the flash and re-installed a couple of hours ago -- Bingo! now I have a blank window again. So flashblock it is. Also, I noted in my first post that I use pclos (an rpm-based, non- debian-derived distro), so it has nothing to do with ubuntu repos. Too bad, I'll have to find a replacement for that, but nice to have the problem trouble-shot anyhow. Thanks guys. -- firefox 3b5 crashes after a blank windows pops-up https://bugs.launchpad.net/bugs/234169 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
