Don't bother installing Youtube AutoPlay Stopper no longer works with the new updated Youtube layout for Firefox v18 but I have found another Firefox add-on that does same thing called 'SmartVideo' by Ashish and go to preference then tick the "Save Bandwidth" box and now all the Youtube videos will stop auto playing until you are ready to press play button. Enjoy!
