How to add breakpoint to a javascript file using a chrome extension

Question

I am trying to add a break-point to the source JavaScript file using a chrome Extension. But it says the

chrome.browserAction.onClicked.addListener(function         


        

Answer 1

The documentation says the parameter name is location, not Location.

In javascript Capitalized identifiers denote classes commonly, while the variables/parameters use lower camelCase.

P.S. to see what actually happens it's very useful to "sniff" the debugger protocol while doing the action manually in devtools.
