Auto-hide all toolbars in fullscreen

When I enter fullscreen mode I'd like all toolbars to auto-hide, and maybe only show when I move my mouse to the top edge, or when I hit Cmd+L or such. Other windows that are not made fullscreen should keep their toolbars in place.

My reason for going fullscreen is to have the entire screen dedicated to the current website / webapp. It's no use getting rid of the OS toolbars if I can't get rid of Firefox ones.

Chrome calls this feature Presentation Mode, it's in the View menu right above Full screen. The latter does not hide toolbars, just like Firefox's. So I guess what Firefox calls "full screen" is actually consistent with that of Chrome, but it lacks Presentation mode. Is there an option or an extension to add it?

Also note that this is very different from the various Kiosk mode extensions. I don't want Firefox to start fullscreen, to limit browsing to the current website, to disable right click and keyboard shortcuts, and all the other limitations put in place by Kiosk mode extensions.

You can use full screen mode by pressing F11 on your keyboard. In full screen mode all toolbare are hide and you have the website in a full screen mode.

When I press F11, the browser goes fullscreen, but no toolbar is hidden.

That's why I asked this question.

I can try with a blank profile, if you think Firefox (on OS X) should do what you say.

You can right-click the toolbar when in full screen mode and set the check-mark on Hide Toolbars (about:config - pref: browser.fullscreen.autohide)

Re: Auto-hide all toolbars in fullscreen

I just tried with a blank profile and I confirm that it's not caused by any of my extensions or settings.

cor-el, my context menu on the toolbar, while in full screen, does not have that option. I only see Navigation Toolbar, Bookmarks Toolbar, Add-On Bar, (separator), Tabs on Top, Customize

  1. In the Location bar, type about:config and press Enter. The about:config "This might void your warranty!" warning page may appear.
  2. Click I'll be careful, I promise!, to continue to the about:config page.

Searche the string "browser.fullscreen.autohide"

That's weird. My setting browser.fullscreen.autohide was already set to true, but it doesn't work. Changing it seems to do nothing. I've entered and exited fullscreen, restarted Firefox… nada.

Re: Auto-hide all toolbars in fullscreen

You can check for problems caused by a corrupted localstore.rdf file.

Start Firefox in Safe Mode to check if one of the extensions (Firefox/Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Firefox/Tools > Add-ons > Appearance).

  • Do NOT click the Reset button on the Safe Mode start window.

Re: Auto-hide all toolbars in fullscreen

I just tried Safe Mode. Still nothing. The default setting is true, but it doesn't work. I tried changing it back and forth, and going back and forth into fullscreen, but nothing. The toolbars are always shown.

Could it be because I'm on Mac OS X 10.7 Lion, that has its own fullscreen support? (Which Firefox is using since version 14)

If anybody else with OS X Lion or newer can confirm this behaviour, we might have to file it as a bug.

On Mac you would have to use Command+Shift+F to toggle full screen mode.
