Sorry, I just remember reading it somewhere and I think it was more likely I got confused with the announcement that web-ext supports Fenix: https://github.com/mozilla/web-ext/releases/tag/4.1.0 https://github.com/mozilla/web-ext/releases/tag/4.1.0 So developers can now test for Fenix but there's no permanent solution yet, unless there was something else and I just can't for the life of me find it anywhere. Sorry for getting your hopes up!
