Just a few minutes ago it was fine. I didn't go into about:config before this.

Nothing happens when you press F11? Try checking this preference:

(1) In a new tab, type or paste about:config in the address bar and press Enter/Return. Click the button accepting the risk.

(2) In the search box in the page, type or paste autohide and pause while the list is filtered

(3) If the browser.fullscreen.autohide preference is bolded and has a value of false, double-click it to restore the default value of true

Using latest FF on Win7 64bit. Everything else is great.

Thank you. The following worked without that retarded popup that tells us its Full Screen. As if we can't tell.....

browser.download.autohideButton true browser.fullscreen.autohide true devtools.command-button-noautohide.enabled false devtools.popup.disable_autohide false ui.popup.disable_autohide false

I was wondering if anybody has ever encountered an extension that sets it at Full Screen by default so every new window/tab is Full Screen? One does wonder why Firefox would wouldn't elect to add that to the options from the very beginning? I never use my Menu Bar. And Alt+D brings up the Address Bar and Menu Bar when in Full Screen though it should just bring up the Address Bar.
