ADB (USB) is activated in the Android settings and adb devices lists my device.
remote USB Debugging in the settings of my Firefox (Android) is turned on.
The two checkmarks in the settings of my inspector for remote debugging and addon development are checked.
I open about:debugging and activate the tools.
The phone shows up on the left but is stuck in waiting for browser.
The following command didn’t work out for me (is it still necessary?):
Note that you can’t debug Nightly from Dev Edition. The client (desktop FF) should always be the same version or more recent than the server (mobile FF). Nightly is always more recent than DevEdition.
That being said, you should still be able to see the Browser (just tried right now).
Make sure you have both USB Debugging enabled in Android settings and in Firefox Nightly settings. Older versions of Fenix required to have a tab opened to see the browser, but I don’t think this is the case anymore.
You don’t need to run any adb command to setup remote debugging. It looks like you have enabled USB debugging in Android settings (I don’t think you would see the phone otherwise). Maybe try disabling USB debugging from about:debugging. Kill any adb process still running. Then re-enable USB debugging?
Can you share which phone you are using here?
(unfortunately we don’t have a good way to get connection failure logs here )
For anyone wondering what the resolve was - for me encountering this issue at least, was to not only enable USB debugging on the android phone’s settings, but also in the Firefox app (Setting > Advanced > Enable USB Debugging). Only then did I get the option to connect.
Google’s LLM provides better documentation than Google itself returns: [1]
