Off-topic:

I will still contribute to upstream UXP for issues that I think you all would want merged in.

I'm glad to hear that. As for the other parts of your post, my response to them has already been echoed. I do hope you keep the spirit of cooperation as the project depends on it (and really, all open-source projects do...) I don't think anybody here has vitriol or the like against you, more just exasperation at the situation. Your knowledge and drive for improvement is certainly welcome.

But it looks like there is interest in things like WebExtensions and e10s? Or I'm wrong?

It seems that's 2 of the things they wish to include in their fork, yes -- I suppose e10s is meant to be a temporary thing, as ownedbywuigi mentioned above. This is why I mentioned I suspect they came to the conclusion that this isn't what the userbase desires. It's unfortunate that the fork happened, and it's exceedingly childish to do so with zero desire for mutual discussion other than vaguely reopening issues (at least on Basilisk-Dev's part), but things like this happen sometimes. It's a nice lesson for the posters here on the value of communication.
