Yeah, I’m the same - Safari, DuckDuckGo, and AdBlock works just fine for most purposes.
Firefox has taken the “continuous delivery” model to the point of absurdity, putting out public releases so often that the best reason to use it - its extensions - are frequently broken because of the updates. Plus, it’s a complete hog (and I’ve used it on three different OSes, and that’s true for all of them).
Chrome = Google = collecting data on you. No way.
Opera has a good reputation, though I’ve never used it on a Mac. The others I’m unfamiliar with.
What is Waterfox?
Waterfox started back in March 2011 when I was just 16 years old. I had a fascination for the web and wanted to help expand on the ideals of what Mozilla had for a free and open web. So I made Waterfox, a 64-Bit variant of Firefox.

I'm not saying this is a bad thing. Just information.
