jquery can't detect window height in Firefox mobile (value returned is too high).
jquery-1.11.1.js:10224
// Either scroll[Width/Height] or offset[Width/Height] or client[Width/Height],
// whichever is greatest
return Math.max(
elem.body[ "scroll" + name ], doc[ "scroll" + name ],
elem.body[ "offset" + name ], doc[ "offset" + name ],
doc[ "client" + name ]
);
dolPopup can get invisible in Firefox mobile.
inc/js/jquery.dolPopup.js:192
Fix might be
inc/js/jquery.dolPopup.js:198 if(!$.browser.opera && !$.browser.firefox) {
I have no device to test it on.
