Chrome Dev Tools hitting code but not breakpoints

Viewed 13759

I have breakpoints enabled on chrome dev tools and I have a breakpoint on a line. I know chrome is hitting the line because I put the breakpoint on a line that has the following statement: alert("why is this not breaking") The breakpoint works if I find the file in the localhost. The breakpoints used to function in the local editor but now they won't. Has anyone else had a similar problem?

You should enable the setting to stop on any exception, in the Sources tab on the developer page (F12 in chrome). (Unload your other extensions to help focus only on the problem one, and remove their thumbnails on the left panel too).

There may be an exception thrown earlier than any debug breakpoint you have set. E.g. there if there is a missing extension permission requirement in the manifest file, which causes an exception to be thrown once it tries to use the resource but can't.
