Worldwide Youtube and Safari problem has started. People are posting on all sorts of forums around the world. There are no player controls with YT videos when viewing on Safari. People have tried everything from rebooting to re-installing to disabling developer menu to various other tricks. YT videos still have full controls with other browsers on OS X. It's like Apple has done something secret to stop YT videos from playing because YT HTML5 videos work fine. Unfortunately, there are thousands of YT videos without HTML5 so we need a fix fast. Any ideas?
