Not sure what the right place for this is; I wasn't able to find a Firefox support forum specifically for web developers. If anybody knows of a more appropriate forum, please let me know.

I'm trying to intercept the opening of a popup window from JavaScript, but I can't find any way to trigger the debugger on this condition, and I don't want to set the breakpoint manually because the source I'm working with is obfuscated and it would take a lot of work to track it down manually. I currently have Firefox 68 ESR, but I could upgrade if needed. Does any version of Firefox have a way to set a breakpoint on new tabs/windows opened from JavaScript, or is there a way to break on the `window.open` function which I suppose is what is being used?

Well I prettified the source and discovered the popup was actually caused by a form element created and submitted from JavaScript. Still interested to hear if anybody knows how to intercept `window.open` popups though.
