User agent spoofing seems like what should be done on the user's end in those cases, if it's not possible to avoid using such sites for whatever reason.

Problems would begin once we'll eventually get Chrome-specific functionality or something that Mozilla won't implement due to a variety of concerns, thus simply breaking sites: https://mozilla.github.io/standards-positions/

Then we'll basically be back in the days of IE, except that this time Google will be the ones with the browser monopoly, if we're not already there somewhat - the majority of folks haven't even heard of Firefox.

Didn't Google say it was going to make Chrome have the same generic user agent forever in the future? Seems like using that one will be the way to go once that happens.
