I mainly use Opera and Firefox.
Opera without cookies enabled and it always remembers the no instant preference, in fact I don't think it even offers me it.
Firefox with cookies but no instant turned off and I only have to re-set when I clear out my cookies...I think!
I'm so used to automatically turning it off I honestly can't remember when it happens but I do know I simply hate instant with a passion.
