If Firefox pushes this before implementing support for extensions (namely uBlock or other ad-blocking / privacy extensions) then Firefox is well and truly toast on Android. Correct me if I am wrong but the only reason non-tech people use Firefox on Android is to block ads. Perhaps this is a push from Mozilla to try and get some search revenue flowing again?
Can someone with Firefox for Android nightly confirm whether extensions are actually not available with this new release? I agree that this would be a cataclysmic regression for Mozilla, if that is indeed what they plan on releasing.
I think it's good to consolidate the branding but this is a half-finished preview replacing nightly, a step backwards.
