Firefox mouse gestures suddenly stopped working.

My back or forward page now only see to reload the page instead moving back or forward a page. This was working fine seemingly no changes. The other odd thing is that when browsing a site like Reddit, once the back gesture is done and it is within the same site, the previous page displays for a split second then back to the current page. I hope this makes sense. All other gestures work even in Chrome.

Firefox=26.0

about:config=browser.gesture.swipe.left, string, Browser:BackOrBackDuplicate

OSX=10.9.1, MacBook Pro (late 2013)

Mouse Settings=Swipe with one or two fingers enables with nothing else enabled.
