Chosen solution

Add code to the userChrome.css file below the default @namespace line.


@namespace url("http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul"); /* only needed once */

#nav-bar[inFullscreen="true"] { display:none!important; }

The customization files userChrome.css (user interface) and userContent.css (websites) are located in the chrome folder in the Firefox profile folder.

  • create the chrome folder (lowercase) in the <xxxxxxxx>.default profile folder if this folder doesn't exist
  • use a plain text editor like Notepad to create a (new) userChrome.css file in the chrome folder (file name is case sensitive)
  • paste the code in the userChrome.css file in the editor window
  • make sure that the userChrome.css file starts with the default @namespace line
  • make sure that you select "All files" and not "Text files" when you save the file via "Save file as" in the text editor as userChrome.css.
    otherwise Windows may add a hidden .txt file extension and you end up with a not working userChrome.css.txt file
