Oh, and DuckDuckGo as search engine. Sometimes I still go to Google, but less and less do I find it useful.
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.
