I'm actually a bit optimistic about it. I know Mozilla has reached-out to uBlock Origin before (I believe it had something to do with uBlock Origin's UI) in what I would consider to be a positive light.

It's also why I'm very interested in hearing what, if any, Raymond Hill's (author of uBlock Origin) thoughts on this matter.

Yes, Gorhill has published the communication between him and Mozilla when working on the mobile UI for firefox Android. It was all pretty great to see.

It's on the very short list of hand-picked available-on-Android (iOS doesn't allow it at all) extensions, so I think so.

I think it was actually the first extension available in the new FF Android version, it’s availability was the reason for me to switch as I need no other extension on mobile.
