Unknown Firefox Virus

My Mozilla Firefox went haywire and now there all kinds of problems. The first thing I noticed was that Youtube refused to play videos. Also, while my pop up blocker is running, pop ups constantly come up on Internet Explorer while I'm using Firefox and IE was not running at all before the pop ups. Also, the keyboard on my laptop shorts out one of every five keys typed. These problems do not at all exist on IE and I am really confused and frustrated. Any Help?
