Desktop browsers too, in fullscreen

Note: These URL bar issues are inherent only to mobile platforms so all the above discussion implicitly applies only to the mobile versions of each browser.

Nope! Firefox in fullscreen has the same problem. Tested it now with

$(window).resize( function() {
  alert("URLBarSizing problem!");
});

The damn thing animates too, so it produced about 14 alerts.

Internet Explorer also has a receding URL bar in fullscreen mode.

This is true, Firefox has a hide-able URL bar on desktop.
Actually, trying out http://bokand.github.io/demo/urlbarsize.html on Firefox, it has some very odd behaviour:

1. Load the page up in Firefox, notice how all the light-coloured text boxes are the same size.
2. Now press F11 to switch to fullscreen mode. Notice how the text boxes are now different lengths.
3. Then, press F5 to reload the page. Now they line up again! What?! Why does reloading change the layout?
4. Exit fullscreen with F11, they're all different again!
5. Reload again, and they line up again.

This is strange behaviour, not to mention that the bars that are meant to change size never do, even when they are given in the same units of vh. Why are the only text boxes that grow the ones that are sized as vh in a percentage-based bar...
