Multi-process Firefox, coming to an Internets near you Chris Pitchin’ Hey

"The fun comes when I kill -9 this gecko-iframe, the “tab” containing mozilla.com. To the non-geeky, invoking kill -9 on a program causes it to crash IMMEDIATELY. This simulates what would happen if, say, you tried to run a buggy plugin and it got itself into trouble. Notice that only the “content” disappears when the page crashes; the user interface itself keeps running as if nothing happened. This is a big step forward! If I were to kill -9 the current version of Firefox, everything would die, user interface and tabs."
