Completely hide title bars?

[oh gosh]

Is it possible? I find them to be fairly useless. Ideally, the title bars would only appear when holding the WIN key, but I doubt that's possible.

Is there some trick I can use to rid myself of titlebars across all windows? I've seen Firefox popups without them, so it has to be possible on some level, right?

The closest thing I know to that in Windows is the F11 key when in IE will force you in kiosk mode or full screen mode with no title bar, no menu bar, no nothing except a web page. F11 again brings it all back, or you can move you cursor to the top of the screen and it pops down from hiding.

I'm also interested in completely hiding titlebars (along with the min/max/close buttons). It would be especially useful for adding browser real estate (without having to deal with the limited functionality of fullscreen).
