Another FFFU (FireFox FuckUp) was removing the 'New Tab' from the Right-Click Tab Menu, somewhere between versions 4.0 and 12.0 (aka ver 4.8). - I actually USED that and MISS it !
Can I get it back ? (in the about:config jungle)
BTW, those holes you posted were not from bullets - They happened when Dolly Parton bumped kinda hard into a wall.
