I have Firefox 6.0.2 and Lion along with a few add-ons. I've been having issues with youtube/flash videos. Here is what my youtube looks like after a while. When I restart Firefox, everything works fine, for a few hours and then this happens. http://i.imgur.com/vgCBt.png Here are my add-ons. I have a suspicion that Adblock Plus is causing it, but I have it disabled on Youtube, but still running, and it happens. http://i.imgur.com/zXJDc.jpg Any ideas? I've tried reinstalling the add-on, Flash and Firefox with no success.
