Firefox won't go full screen, taskbar does not hide.

Posted

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?
