Safari is a good browser due to it being the most battery efficient on MacOS.

However its content blockers are inferior to what's available on Firefox. It's also not portable, so if you use various devices (Android, iOS, Windows, Linux, MacOS) it's pretty cool having your history synchronized.

Firefox is really good for privacy. For example you can sandbox Facebook with Firefox's containers extension such that they can't follow you around the web.

Firefox is probably the best for power users. I usually use it with more than 100 tabs opened. Its tree-style tab extension and the Awesome Bar makes it painless.

Firefox is also good as a development browser. It lags behind Chrome in some areas but is ahead in others.

At work I only use Chrome for testing our web interface, but I use Firefox most of the time, even on my iPhone (nice UI plus the sync).

Safari has blocked third party cookies, as well as the largely unknown segregated cache and localstorage, and now some form of tracking protection. That should make it equivalent to Firefox containers, although it’s just automatic and kind of invisible to the user. As for blockers, I use 1blocker to great effect. I’d use uBlock Origin but the transition to MAS seemed to be rocky last time I checked.

I do give it a spin regularly but the two things that make Firefox a non starter is battery usage and inability to use Keychain (before quantum there was an extension but even then it was hit and miss)
