There's some de-googled Chrome options and I guess some weird special-build Firefox options, but really, out of all the options I see, FF is best for me.
Un-googled chromium is one. I suppose that I trust Mozilla marginally more with my user data than Google.
But yes, I agree, the browser landscape is pretty lousy right now.

I perceive this to be the continuation of a trend.
I think FF still has value for now, but it seems like that value is pretty quickly dropping - as a piece of software, if not from a philosophical perspective (supporting the open web and all that).
