I've got a Toshiba Win 8.1 tablet here from a friend and it is frozen on a webpage.

I go to the yellow tile named Desktop and open it up. Now all I see is the mozilla firefox support page. No menu, no toolbar, no X in the corner to stop the thing. Nothing like : "press here to return to desktop." If I sweep it from top down then the desktop app stops.

I would do a right click on the taskbar and call up the task manager to kill the process but this is a touchpad thing and I am crippled.

I want to stop the firefox browser remove it from the taskbar and rip it out and watch it die. Where do I start?
