title: Firefox/Chromium plugin to catch all AJAX requests?
body: <p>My situation is as follows: I have some Javascript code that I did not write myself, but I that I would like to get acquainted with (actually, I want to debug it). In particular, I am interested in what AJAX requests this code makes, and when.</p>
  
  <p>This Javascript code I'm looking at is quite complex and lengthy and chaotic. So basically, just <em>reading</em> the source code or grepping the source code for this or that function call is not a good option. What I would like is some Firefox or Chromium plugin (whichever works) that does the following:</p>
  
  <p>While loading the page and executing the Javascript, I would like it to catch any AJAX request that is made and tell me about it (most importantly, what URL is being called, though knowing what POST parameters etc. are travelling along that request would be useful as well). It would be awesome if it actually stopped before each execution of an AJAX request, told me about it, and asked me if it should proceed. But I would also be happy even if it did nothing else but simply print each URL that the Javascript sends an AJAX request to into a console or something.</p>
  
  <p>Any suggestions?</p>
