TCP Port should be configurable

This is a good starting off point

Maybe this one will help me, sadly i still feeling unfamiliar with the code base.

hmm, what's your issue again? if it works w/ websocket then just make that the default for you

[sukrosono]

Am i wrong?

i'm not sure... we all get the json/list error because it's trying to fetch the tabs for a firefox that's not necessarily open. The key is to launch a firefox that you can then inspect, there are two ways. open firefox yourself and follow these steps: https://github.com/devtools-html/debugger.html/blob/master/docs/getting-setup.md

2. use the launch firefox button which might not work for windows/linux

the button under the hood is doing the same thing too: https://github.com/devtools-html/devtools-core/blob/master/packages/devtools-launchpad/bin/firefox-driver.js#L41-L70

it's just a helper :)
