Furefox just upgraded me to Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:220.127.116.11) Gecko/2009040821 Firefox/3.0.9 (.NET CLR 3.5.30729).
Now BF is all messed up. There are gray bars on the right hand side where the advertising normally is. It makes the left side with the text very narrow. Is anyone else seeing the same problem with their upgraded FF?
