Control+Command+F, as visible via going to Safari > Menu Bar > View > Enter Full Screen.
Full screen mode is great.
But I would like to hide the address bar and tabs. I am hoping I can make a website use the entire screen. Currently the address bar and tabs take up more room then i would like. In Chrome, hitting F11 will make the website fill the entire screen. Really nice for sites like Reddit and forums.
Sorry, misunderstood, just got out of bed.
There seems to be no way, as even if you hide the tool bar (Shift+Command+T) before going to fullscreen, it will return when going to full screen, maybe just using one window instead of one tab will allow you to get rid of the tab bar.
What screen resolution do you have, that those 62 pixels take away from your enjoyment?
