There is a similar bug reported in Firefox Bug Tracker. One of the workaround mentioned there (which works for a few people) is to set gfx.xrender.enabled to False in the about:config settings page of Firefox.

Type about:config in the Address Bar and search for gfx.xrender.enabled in the search box. Double click the item to make sure its value is False. Then restart Firefox and see if it works for you.

Set gfx.xrender.enabled to false in about:config

The Question is Closed, Thanks to Aditya. – bx758 May 9 '14 at 7:13
@bx758: Closing a question has a different meaning on Ask Ubuntu. The correct term would be, the question is answered to satisfaction or the answer is accepted :-) – Aditya May 9 '14 at 8:15
ok sorry. question is accepted ;) – bx758 May 9 '14 at 9:40
