Question
Flash does not work with Firefox following Windows Vista update 14/5/2014.
Flash still works with IE9. I've carried out all steps in http://helpx.adobe.com/flash-player/kb/flash-player-games-video-or.html, i.e. twice updated Flash to V13.0.0.214 (previously V13.0.0.206), activated Firefox Flash add-on, deleted browser data and cache and disabled hardware acceleration. Nothing fixes it! Vista SP2, Firefox 29.0.1.
