I love this feature, but I only use it about twice a year and it seems like evertime I go to use it again, it does not work. I've tried in Chrome and in Firefox. Chrome has the extension installed and is what I've used in the past. Neither Chrome nor Firefox will connect to PHPStorm's debugger. Both applications launch when I start the debugger, and then nothing.
I'm not even sure what else to look at.
Chrome launches, but does not even navigate to the page, Firefox navigates to the page, but still does not connect to the debugger.
My preference is to use Chrome.
