For a temporary workaround (by no means a fix), try using the HTML5 version of YouTube here: http://www.youtube.com/html5 . Also, what do you mean by "adobe flash wont work"? Do the videos not play? Does it show the loading bar and not play, perhaps?
** Changed in: firefox (Ubuntu) Status: New => Incomplete ** Description changed: - THe you tube will not play and the adobe flash will not work + YouTube will not play and Adobe Flash will not work. This has been going + on for the last ten days, and nothing I do seems to work.
