Notes"For a long while now (even before Google Chrome was announced), Mozilla has been examining ways to make Firefox better by splitting the work of displaying web pages up among multiple processes."Unfurl
Notes"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."Unfurl
