I use Firefox, and I've considered using Ungoogled Chromium, but I'm hesitant do so because there are no official, authenticated binaries (see readme notes [1]).

As far as I recall, Ungoogled also doesn't offer automatic updates, probably for the same reason.

I also dislike the fact that it's actually a fork that adds features that have nothing to do with "ungoogling". But that's a minor point.
