Async JQuery brakes CrellySlider

I don’t know why, but I don’t have this code in this lines. From 161 to 179 on my server I have some totally different code(I got latest version of CrellySlider). I also went to github(https://github.com/fabiorino/crelly-slider/blob/master/wordpress/frontend.php) and check it there, just in case, there’s also some different code in this lines. But I found it on my local between lines 431-467. And this is the code:
$output .= ‘<script type=”text/javascript”>’ . “\n”;

$output .= ‘(function($) {‘ . “\n”;

$output .= ‘$(document).ready(function() {‘ . “\n”;

$output .= ‘$(“#crellyslider-‘ . $slider_id . ‘”).crellySlider({‘ . “\n”;

$output .= ‘layout: \” . $slider->layout . ‘\’,’ . “\n”;

$output .= ‘responsive: ‘ . $slider->responsive . ‘,’ . “\n”;

$output .= ‘startWidth: ‘ . $slider->startWidth . ‘,’ . “\n”;

$output .= ‘startHeight: ‘ . $slider->startHeight . ‘,’ . “\n”;

$output .= ‘automaticSlide: ‘ . $slider->automaticSlide . ‘,’ . “\n”;

$output .= ‘showControls: ‘ . $slider->showControls . ‘,’ . “\n”;

$output .= ‘showNavigation: ‘ . $slider->showNavigation . ‘,’ . “\n”;

$output .= ‘enableSwipe: ‘ . $slider->enableSwipe . ‘,’ . “\n”;

$output .= ‘showProgressBar: ‘ . $slider->showProgressBar . ‘,’ . “\n”;

$output .= ‘pauseOnHover: ‘ . $slider->pauseOnHover . ‘,’ . “\n”;

$output .= stripslashes($slider->callbacks) . “\n”;

$output .= ‘});’ . “\n”;

$output .= ‘});’ . “\n”;

$output .= ‘})(jQuery);’ . “\n”;

$output .= ‘</script>’ . “\n”;`

But that’s alright. The thing is, it doesn’t work in FF(IE edge and 10, chrome, opera – works great).
But in FF this is what happens:
When I open the page with the slider, it doesn’t load. No matter how much I refresh the page. BUT! If I click on the link to this same page(I clicked on the logo instead of refreshing by accident) and this time slider did load normally! I tried again and again and this works this way. But only this way. It doesn’t fire if I simply load the page or opening normally. Any idea of why this could happen? I tried also change the delay time from 100 to 1000, to see if it helps, but its not.

It’s not really important, but somehow I got frontend.php with lots of empty lines(not huge, but there’s a difference in between the original).

As for the firefox: I of course checked it with empty cache. Also, I tried it with fresh version of the pre-installed themes – works the same. Also I played around, but nothing really helped. However there’s two things I think I should mention:
1) This is what I’m getting without hitting the local link to the same page: Image
2) I found this link while searching for solution and playing around with it: http://forum.jquery.com/topic/setinterval-not-working-in-firefox
So I tried this updated code:

$output .= '<script type="text/javascript">' . "\n";
$output .= 'var fileInterval' . $slider_id . ' = setInterval(function() { if(jQuery.fn.crellySlider) {'  . "\n";
$output .= '(function($) {' . "\n";
$output .= '$(document).ready(function() {' . "\n";
$output .= 'var d = new Date()' . "\n";
$output .= 'd.getTime()' . "\n";
$output .= '$("#crellyslider-' . $slider_id  . '").crellySlider({' . "\n";
$output .= 'layout: \'' . $slider->layout . '\',' . "\n";
$output .= 'responsive: ' . $slider->responsive . ',' . "\n";
$output .= 'startWidth: ' . $slider->startWidth . ',' . "\n";
$output .= 'startHeight: ' . $slider->startHeight . ',' . "\n";
$output .= 'automaticSlide: ' . $slider->automaticSlide . ',' . "\n";
$output .= 'showControls: ' . $slider->showControls . ',' . "\n";
$output .= 'showNavigation: ' . $slider->showNavigation . ',' . "\n";
$output .= 'enableSwipe: ' . $slider->enableSwipe . ',' . "\n";
$output .= 'showProgressBar: ' . $slider->showProgressBar . ',' . "\n";
$output .= 'pauseOnHover: ' . $slider->pauseOnHover . ',' . "\n";
$output .= stripslashes($slider->callbacks) . "\n";
$output .= '});' . "\n";
$output .= '});' . "\n";
$output .= '})(jQuery);' . "\n";
$output .= 'clearInterval(fileInterval' . $slider_id . ');'  . "\n";
$output .= '}},1000);'  . "\n";
$output .= '</script>' . "\n";

But this didn’t help, unfortunately. Perhaps I just didn’t use it right or something.
