View > Address Bar is also helpful when a f!&$&@g popup tries to hide its origin... this ability to selectively determine UI elements on a per-window-basis is one Safari feature that i'd actually like to see in Firefox...
Thanks, this is one of the reasons i went back to firefox on mac but now i can see locations! With 4.0 being out i just can't resist safari, it loads pages blazing fast often 3-4 seconds faster than firefox.
