Thank you thank you thank you!! The default new tab of whatever FF version I was originally using had tons of media sites making my CPU hit 100%. This is a mid range gaming laptop with plenty of power but still struggled when hit with forced media in multiple tabs. Now with all that stuff disabled on new tabs I'm at 0% or 1% when idling on a blank tab. Also, this eliminated personal privacy issues b/c no longer dealing with 'top sites' or other forced content showing unless I want that content showing. Thx
