Firefox won't go full screen, taskbar does not hide.
Firefox won't autohide the taskbar.
In about:config autohide is set to true. I wanted to try deleting my plist, but couldn't find it. I've turned all the add-ons off and nothing helped.
I'm running OSX 10.10.4 and Firefox 40.0.3

Start Firefox in Safe Mode {web Link} by holding down the <Shift>
(Mac Options) key, and then starting Firefox. Is the problem still there?
Try this extension:
- Old Lion Fullscreen: https://addons.mozilla.org/firefox/addon/old-lion-fullscreen/
This is accidentally a repeat post. Cor-el can you delete this one and refer only to my first post that you already responded to? Thank you!
