I use it, but both Chromium and Safari are better on this platform.
I'm a Firefox fanboy, still use it on OSX because it's important to me, but the amount of random pauses, crashes, etc is just painful on OSX. It's like none of the Firefox developers use it on OSX or something.
And before someone says "oh it's your extensions", that IMO leads to two talking points
1. It's 2020 and major extensions still cause memory leaks in Firefox. Debugging them isn't easy at all. Almost all of the resources say something like "Run in safe mode and see if it fixes things" and then lots of posts of "post your about:memory here and I'll analyze it." I'm a software engineer by trade and it's been difficult for me to diagnose...
2. Nah because I don't run any extensions on my OSX firefox install
As far as "least standards-compliant," I understand that when it comes to supporting progressive web apps, Safari has largely dropped the ball, but in day-to-day practice there just aren't many sites that I have trouble with on Safari. (The biggest one seems to be new Reddit, and I am not entirely convinced that issue is on Safari's end.)
Built on top of KHTML foundation, it then became webkit and later the most successfull engine. It was the first to implement full ES6 support, and basically invented CSS transformations/transitions (really amazing stuff back then but not really used until all major browsers caught up years later), was the first to ditch Flash support, has argueably the best privacy policy, has superb font rendering, etc.
Most people don't care about battery life?
I also stopped recommending it to randos when they started coming back and complaining about weird behavior. Now if I don’t know someone and want them to just have the simplest working experience I recommend Safari on Mac and Brave on windows.
