Is it actually possible to use Firefox mobile remote debuging?

Question

Mozzila decided they don't need error console in their mobile browser, so they instead invented " Remote debugging ", something that would probably be cool if it ever worked. I tried it few times before just for fun, but never got it to connect. Now I really needed and I was also expecting the feature improved over time. Not at all.

Enable on Mobile

To enable remote debugging, you're first supposed to allow USB debugging and then remote debugging in Firefox Mobile. These are just two buttons, so it's no problem. My Firefox Mobile version is 39.0 .

Enable in browser

In browser, as I understand it, WebIDE is used, which is a special Firefox debugger and virtualiser. Can be launched using Shift + F8 . The connected USB device is supposed to appear in menu:

I was wondering why I see Install ADB Helper in menu when it's already installed. It's probably because this:

I guess Firefox hates me.

The question

Since Mozzila obviously disabled their only means of debugging mobile Firefox, I came here to ask for some workaround. With all those mobile web pages I expect lot of you guys know how to debug them. Possible solutions I'm looking for:

1. Debug over IP instead of USB. I am much more comfortable with using WiFi than USB.
2. Force Firefox to enable ADB Helper even though it's incompatible.

Answer 1

1. To get ADB Helper working, update your Firefox desktop version. It looks like you're on 37, which is unsupported, insecure, and ~6 months out of date.

2. Wi-Fi Debugging landed in Firefox 42: https://developer.mozilla.org/en-US/docs/Tools/Remote_Debugging/Debugging_Firefox_for_Android_over_Wifi
