title: Pause Javascript || Freeze page
body: <p>I am wondering if there's some work-around for my "problem".</p>
  
  <p>I play a game which i customize with Javascript/jQuery through Greasemonkey/Firefox.</p>
  
  <p>There are plenty of scripts which modifies the DOM and some input values. On my custom script i use an ajax call which takes around 15-20 seconds to complete, but by that time the page is modified and so i got here.</p>
  
  <p>I suppose i have to somehow stop everything, all javascripts, freeze the page completely until my ajax finishes, but keep in mind that i can't control / modify all scripts on the page.
  From my experience .. everything is possible, am i wrong now ? ..
  Thank you.</p>
