Nightly user here, does this mean I no longer need to do the song and dance of manually adding my addons list to the browser anymore? Guess I can finally switch to stable!
I am also using the same method and hoping the same thing. I doubt we will have to do the song and dance just because it is very much a developer feature test route and they have had extension functionality previously in the regular release.
Also looking forward to pulling back to stable build.
