Is there a method to determine (using developer tools like Chrome, Firefox, Opera, etc) the most recent function that triggers an AJAX call?
This could be helpful for debugging web applications.

My method for analyzing web apps in Google Chrome:
By following these steps, you will obtain a detailed profile similar to the image displayed below. This profile will document all JavaScript calls made during the profiling session, including any AJAX requests, along with the corresponding sections of code where each call originated.
In an additional screenshot example, there is evidence of an AJAX call triggered from a script (dash.js, line 51) within a function named doOnSelectDate(), which was subsequently invoked by another function titled getDailySummary() (located at line 60).
For the stack information you need, check out console.trace().
Learn how to accomplish this task using Firefox and Chrome with the help of W3Schools jQuery example here.
To initiate the AJAX call event, access Firebug console and click on the source link.
If you have your own low-level AJAX function, this should suffice. However, if you are utilizing jquery.min.js, clicking on the link will not be helpful. Set a breakpoint at the specified line (line 6) instead.
Next, trigger the AJAX once more and it will pause at the breakpoint. Navigate to the stack tab to locate your call. Click on it to view the source.
In settings, enable "Log XMLHttpRequests".
Rerun your AJAX operation, and it will display in the console. Expand it to inspect the stack trace.
One useful tool for debugging javascript in Firefox is Firebug. It enables you to set breakpoints within your code.
In Firebug's script tab, you can choose your script file and add breakpoints at every AJAX call to determine which one is executed last.
To access developer tools in Google Chrome, navigate to view -> developer -> developer tools.
If you are looking to monitor network activity, the network tab within developer tools is likely where you'll want to focus.
For debugging and viewing ajax requests, Firebug is a useful tool available as an addon for Firefox.
