I amusing Firefox since long time as my default web browser. Recently I have upgraded to v11.0. but since i upgraded, it started giving me an error message saying ‘Your browser is blocking Flash’. I don’t know why is this error coming up and what is it related but the error only occurs when i open my email clients such as Yahoo or Gmail. But i open the same sites using Opera or Internet Explorer, it works fine. But as i said, i mostly use Firefox, i want to fix it. Could you guys please help ? Am using Windows 7 Ultimate pc.
