Note that you won't be able to use feature available on the toolbar.

Add code to the userContent.css file.


#outerContainer #mainContainer div.toolbar {
  display: none !important; /* hide PDF viewer toolbar */
}

#outerContainer #mainContainer #viewerContainer {
  top: 0 !important; /* move doc up into empty bar space */
}

You need to create the chrome folder (lowercase) in the <xxxxxxxx>.default profile folder if this folder doesn't exist.

  • use a plain text editor (Windows: Notepad; Mac: Textedit) to create a (new) userContent.css file in the chrome folder (file name is case sensitive)
  • paste the code in the userContent.css file in the editor window
  • make sure the userChrome.css file starts with the default @namespace line

If you are on Windows:

  • make sure you select "All files" and not "Text files" when you save the file via "Save file as" in the text editor as userContent.css

Otherwise Windows may add a hidden .txt file extension and you end up with a not working userContent.css.css.txt file.

  • make sure you do not have a double .css.css file extension (userContent.css.css.css) if it is still not working

Note that in this case you need userContent.css

In Firefox 69 and later you need to set this pref to true on the about:config page to enable userChrome.css and userContent.css in the chrome folder.

You can open the about:config page via the location/address bar. You can accept the warning and click "I accept the risk!" to continue.
