How to set breakpoint programmatically in IE extension?

Question

Did some homework on this. I saw one can set breakpoints using debugger in JavaScript source code. However, I am wondering if I could set a breakpoint in IE extension programmatically. Say, once IE discovers JavaScript source code on some callback function, I could set breakpoints via its PC or line#.

No, there's no JavaScript mechanism that allows you to set breakpoints programmatically other than the debugger statement. Your best option would be to express 'decision' and result in an if (something) { debugger; } style statement.

That said, the IE dev tools, like other browsers, allow you to set breakpoints conditionally. All you need to do is to to right-click when you add the breakpoint and then select that it's conditional. In the condition you can enter anything that'll return a true result.
