how do I delete this thead?
I guess there is no answer.
Too bad no button in firefox to say don't use disk....use ram....and when need some expire already loaded non selected tab stuff and re grab it form network if need later
Where is the browser loaded from? If the answer is "The OS I installed on disk" then the answer is obviously no. You could try to set up something virtual, like a ramdrive, but I think it's overkill. Best you leave this handled by the OS.
