Well, I am a Firefox user; not sure where 57+ is going to take things, but it is more likely that add-ons I want to use will become unavailable than available. Right now I have a barney with Mozilla over their mobile version of Firefox and Focus browsers; neither even let you see the content of the TLS certificate! Let alone remove an added override to allow a site to be viewed. Firefox may be the best privacy browser, but as I said in my complaint (via Play store), I don't want to be the M$ employee whom has to open up Chrome because Edge failed him (or Firefox/Focus in my case).
