On my 2 Fedora 8 systems, I have this problem today for the first time. In Firefox, while browsing youtube, my system will crash when opening flv files. Generally, I can view one show, and then when I click another one, the whole browser disappears. It does not lock up at all, it just dies. It does not affect any other programs. I have not gone to youtube for a few weeks, and so I can't say if this problem is actually new, or if I just happened up on it. Would you please browse to youtube and try to watch a few and see if you get the same outcome? If you don't, it will mean I've made the exact same configuration mistake on both of my systems. I've moved ~/.mozilla and ~/.macromedia out of the way, same result. Here are the version numbers: $ rpm -qa | grep flash libflashsupport-000-0.1.svn20070904 flash-plugin-9.0.115.0-release $ rpm -qa | grep firefox firefox-devel-2.0.0.12-1.fc8 firefox-2.0.0.12-1.fc8 $ uname -r 2.6.24.3-34.fc8 Another thing in common is the Nvidia proprietary driver from livna. pj -- Paul E.
