For quite a while, it has been possible to debug tabs on Firefox for Android devices, but there were many steps involved, including manual port forwarding from the terminal.
How to Use
You’ll need to assemble the following bits and bobs:
- Firefox 36 (2014-10-25 or later)
- ADB Helper 0.7.0 or later
- Firefox for Android 35 or later
Opening WebIDE for the first time should install ADB Helper if you don’t already have it, but double-check it is the right version in the add-on manager.
Inside WebIDE, you’ll see an entry for Firefox for Android in the Runtime menu.
Once you select the runtime, tabs from Firefox for Android will be available in the (now poorly labelled) apps menu on the left.
Choosing a tab will open up the DevTools toolbox for that tab. You can also toggle the toolbox via the “Pause” icon in the top toolbar.
If you would like to debug Firefox for Android’s system-level / chrome code, instead of a specific tab, you can do that with the “Main Process” option.
We have even more connection UX improvements on the way, so I hope to have more to share soon!
