When I watch Youtube or the BBC news feed I can usually get the video. But other sites won't work. and I get a squiggly mess all over the screen. If I copy the web address and put it in Google Chrome it works. I also can't get Apple QuickTime movie trailers working but I don't think that's Firefox. Not sure. I use Ubuntu 9.04 Jaunty. I use Firefox in my online business and depend on its stability so this is very urgent for me. Thank you, Darrell Hare
