How to Disable Toolbar Auto-Hide Feature in Full Screen Mode of Mozilla Firefox

Whenever you go into Full screen mode in Mozilla Firefox by pressing F11 key, the tab bar and toolbar auto-hide to save space. You need to move your cursor on top of the screen to bring them back.

Some people might like it but others might want to disable it to quickly access the toolbars.

In this tutorial, we'll tell you how to disable the auto-hide of toolbars in full screen mode:

Method 1:

1. Open Firefox and type about:config in the addressbar and press Enter. It'll confirm, click on I'll be careful, I promise! button.


2. Now type autohide in the Filter box and look for following boolean key:


3. The entry "browser.fullscreen.autohide" would be set to true. Double-click on it and change its value to false

4. Now whenever you go into full screen mode, you'll always see the toolbars.

  • i used the second method
    thank you for the information!

  • There is no address bar when I click F11 there is a click sound but nothing happens

  • I'm looking for kind of the opposite. I'd like my non-full screen windows to autohide the addressbar. So far I've found no reference to this feature (it might not exist).

  • I'm also looking for kind of opposite :).
    I'd like to hide the addressbar, tabbar and any other bars completely. Yes, even that annoying one-pixel-wide line at the top of the window in fullscreen mode. An I also don't want any bar jerk off, when I hover my mouse over the edge of window. Will FF ever make it to the level of the deceased Opera...?

  • I want to lock webage in a full screen mode I dnt want to see the toolbar

  • Hi,
    Thanks very much for this tip - it worked! Relieved! :) I'd just like to add one helpful thing though - typing 'animate' in the Filter/Search ('Search' was on my screen) on the about:config panel didn't display the boolean key 'browser.fullscreen.autohide' for me at all. But when I typed in 'autohide' in the Filter, it DID show up. So, if anyone else has this minor problem, just type 'autohide' and that should work!

  • there is no f 11 key no f keys on my keyboard

  • I used the first method and it seems to have worked. Thank you! I found that my (newer?) version of mozilla doesn't make me promise to be careful, but leads directly to a screen where you can search browser.fullscreen.autohide.
