After the last update firefox has become very slow. The slowness is different, it runs like a step motor. For example, if I hover the mouse on some link, it takes a while for the mouse icon to change to hand-shape, after clicking the link it again takes some time for the link to open in a new tab and in the meanwhile the new tab which opened as a result is frozen. I hope you get the idea. It becomes really irritating while watching you tube videos, in full screen mode the video plays like one frame at first then another frame after 5 seconds.
Is anybody facing similar issues with firefox? How can I improve the performance of ff?
