.. that should've been part of Firefox. So now that they "redesigned" the browser once again, and forced the "Box model" into an inconvenient location, I had to use this wonderful addon to identify and hide it. (#layout-wrapper { display: none; } in userChrome.css)
So Firefox is dying.. and donations are appreciated.. too bad I feel like donating to SeaMonkey Council instead of Firefox. :(
Thank you for DOM Inspector!
