I am trying to debug a third-party HTML/Javascript page but I can't easily locate the script entry points to set breakpoints on them. I want the debugger to break on any element's onclick event handler. At the moment if the page is set up with something like document.getElementById("foo").onclick = bar; then in general it isn't easy to determine that foo and bar are connected. So, I want to break on all onclicks, wherever they may be. Can I do this in Chrome or Firefox?

Chrome:

Chrome inspector -> sources -> Event Listener Breakpoints

Firefox: get EventBug

You can read a bit more about eventBug in here: Using Firefox, how can I monitor all JavaScript events that are fired?
