As mentioned in the title, I had a problem so that Firefox could animate a container element with the class name .mover - left: 0% and back left: 100%.
I have compiled an example here. http://jsbin.com/ucefig/28
Scroll down to the yellow βwho we areβ page, then select the black box, this should animate the .mover element on the left. Click it again on the "our people" page, and it should return to its original position.
My code works on IE9, Chrome and Safari, but it doesn't work on Firefox.
the picture illustrates my dilemma in the example above, the gray square is the .mover element that is animated, the squares are pages. in FF.mover topscrolls to 0, and then animates to the left into the void.

Thank you camera
