Yeah, but then I have to have a "guest" log-in. My computers are always on, so people never feel bad about asking to use them, and I feel it's unnecessary and unsmooth to log out.
Since I've already been perfectly demanding|whining about a feature I'd like to have, what I _really_ want is to just click a program that boots up a vm with the same OS, but only the browser ready to go with a fresh lack of cookies, history, etc.
Ubuntu already has a "proper" guest mode, only accessible when unlocked by a regular user, wiped clear each time and only providing access to the guest sandbox. It's available from the system menu, so two clicks to activate when logged in already, or a couple of clicks and a password if the machine is locked (and in that case you don't have to go through your regular desktop to get to it).
In Windows you'd hit Windows-L, which would take you to the login screen, and then they'd click "Guest" (or whatever alternate login you've set up). You'd still be logged in, and when they were done (or were giving it back to you for five minutes) you press Windows-L again and choose your own login to switch back to your still-running programs.
I'd be astounding if Linux didn't have an equivalent.

IS THAT REALLY SO MUCH TO ASK? </overdramatic>
