after updating firefox 3.6.3 to firefox 3.6.4 besides a extremly mangeled my yahoo website (no images just texts and search bars) and 404 not found errors and their less common 400 bad request errors i dont get anything NOTE: you know the main search bar with the long search bar that displays the website address and the small yahoo/google search bar the http bar tends to give the 400 error while the regular search bar gives 404 errors. NOTE 2: all of the older versions of firefox (3.6.3 and older) seem to work just fine so does internet explorer == URL of affected sites == every site i know of im using explorer right now
