I moved from Firefox to Palemoon a while back and use it with a few extensions, including Secret Agent. Quite nice for poisoning any fingerprinters. It's Firefox with a few settings for privacy set by default.

The only issue I have with it is it's default homepage points to https://palemoon.start.me/start which is powered by startme.com. But that's easily changed.
