When I used ionic before, and I browsed the documentation at
http://ionicframework.com/docs/components/, the phone showing the example at the top of the page would move down as I scrolled and update with the contents of the documentation.
So for example, if I was at the “responsive grid” section, I would be able to see a phone next to the description showing an example of the grid.
This now seems to be broken on firefox (41.0.1) - the phone stays at the top of the screen and does not update. It works fine on Safari 8.0.6.
I have a workaround for now (use Safari!) but thought it might be good to fix it.
