All Mac windows have a button that is created by the OS, the show/hide toolbar button. It's the little rounded rectangle button in the top right corner of the window, inline and opposite of the three color buttons (close, min, max ;P ).

Why has this button been removed/disabled?

It's my semi-fullscreen button. ^^

Would like to add that this button is present in FF3.6.18 and was removed/disabled in FF4.

Bump. 12 people also want to know the answer to the missing system button.

And to make this bump a valid one I'll attach a visual aid showing you the missing button.

As a temporary solution setting the value:

about:config > browser.fullscreen.autohide to false

will keep the toolbar from auto-hiding.

this doesn't really solves completely the problem, right ? i have the same issue.. have upgraded to firefox 4, but that grey button, the "semi-fullscreen" one, vanished... hope that could be restored somehow...
