CSS3 transform stops presentation on Firefox only

Sep 26, 2014

I have a web site with LMS that runs without problem with Articulate Studio 9/13.
As it runs in a HTML5 enviroment I decided to user CSS3 transform (-moz-tranform or -ms-tranform) to ajust the current fixed site elements to the windows user's browser. I used:
$('body').css('-ms-transform','scale('+indResp+')');
$('body').css('-webkit-transform','scale('+indResp+')');
$('body').css('-moz-transform','scale('+indResp+')');
$('body').css('-o-transform','scale('+indResp+')');
$('body').css('transform','scale('+indResp+')');
$('body').css('-ms-transform-origin','0 0');
$('body').css('-webkit-transform-origin','0 0');
$('body').css('-moz-transform-origin','0 0');
$('body').css('-o-transform-origin','0 0');
$('body').css('transform-origin','0 0');

Where indResp is a javascript variable that contains the new size rate (in percentage) of the user's windows.
Everything works fine, I mean while users runs every page of the site and even while running an Articulate presentation if his/her change the windows size all page change the size to fit in the window and even Articulate continue to run in the new size.
I tested with IE, Chrome, Opera and Maxthon and everything is perfect. When I use Firefox everything works fine also, but when an Articulate presentation starts it shows only a blue or white background. It seems to be the player background and stops to show everything. I can see that the presentation is running checking the Javascript console due to all Scorm messages are sending and even the sound of the first slide I can hear, but the presentation itself do no show up (only the blue screen).
I tried to find on Internet some clue or even complains about that withou success. I tried Articulate support that could not understand what I was explaining (she did not support CSS3 she said) and could not help me.
Are you fellows able to give me some clue or indicated me some document where I can find a solution for this?
Thank you, and regards from Brazil.
