Is Chrome the New IE? (2023)

Just to (mostly) preempt this because the exact same discussion is had every time this sentiment comes up: Isn't safari the new IE?

Answer: They both are like IE, for different reasons:

Chrome: Pushes proprietary extensions onto the web, which due to their absolute dominance others are somewhat forced to adopt, people develop for it and don't test in any other browser, just like IE

Safari: is coupled to operating system version, lags behind on implementing new features, thus single handedly slowing down when everyone can use new features. Has weird quirks that other browsers don't, just like IE (though not nearly as bad as IE)

So which is like IE? It just depends on what you mean when you say "like IE", the label applies to both because IE was bad for more than one reason

What are these proprietary extensions?

if you want a really old example, pnacl. If you want a slightly recent one, FLoC. Not saying those are the best examples, they are just what comes to my head first. I don't really keep up super closely.
