Firefox 4 Forum podrške

Hello,

I'm using Firefox focus for a long time but i wondered why there weren't any add-ons like ublock origin. So i taught maybe the beta or nightly version haves it but that's a no too. So i was wondering if mozilla is gonna work further with firefox focus or did they just dropped it because there weren't really any updates lately except bugs things. Another question how do i remove firefox focus beta and nightly out of the play store?
