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)
