I've recently published a Firefox web extension which works on Desktop browsers and wanted to start now with the port for Android devices. As suggested in https://developer.mozilla.org/en-US/Add-ons/WebExtensions/Developing_WebExtensions_for_Firefox_for_Android , I've installed Android Studio and several Android emulators (Nexus 5x with Android Nougat, Oreo, etc.). However, when I try to install Firefox from the Chrome store, I always receive the "Your device isn't compatible with this version." message. This is very frustrating as Firefox seems to be one of the few apps that can't be installed in the emulator (WhatsApp and Opera are installable, Facebook and Firefox are not). I was wondering if the requirements for the app are set (mistakenly) too high? Or maybe I'm doing something wrong? How do you develop/debug your web extensions? Thanks for your help!
