Please don’t list before it is ready for testing. Ask in support channels how to test on a phone.
Well, that makes sense. So I signed app using Web and tried on install phone. But I couldn’t find a way to install addon from xpi in firefox phone. Does anyone has idea how to test on phones?
After you setup everything, you should be able to test your extension even without a phone - just install Android Studio with some Google Play enabled virtual phone and install Firefox there. Then you should be able to execute something like this:
web-ext run --target=firefox-android --android-device=emulator-5554 --firefox-apk=org.mozilla.firefox_beta
Regarding supported API - mostly just make sure to somehow disable all browser.windows calls, since these are not supported (because there is only one window).
