I have a strange problem that I decided to share it with you all. Well the problem is that I have a extended desktop and I have one screen as the computer monitor while the other one is the TV screen. Whenever I drag Firefox browser to the second screen i.e TV screen and if I start playing you tube videos in it in a full screen. Then it does not play in it. In fact it gets back to the normal monitor and starts playing in it. It happens only when I switch to the full screen and not in the normal view. Now why is this happening? If you all have any ideas then do let me know.
