I had also problems with Firefox3 and Flash10 from the backports yesteray. My main problem was the very high CPU and I also noticed slow video playback on youtube and google video. So it is unusable for me. I don't have libflashsupport installed and I'm running Kubuntu, not Gnome Ubuntu.
For the first time in 3 years I had to disable backports to get things back to normal. I never had problems with Flash 9.
