I found out the actual reasons why Safari isn't good on OS.

I found out a reason why Safari isn't suitable for OS.

The reason is the engine.

I wish all the browsers have Chromium but Apple decided to use its engine, WebKit, which isn't suitable for OS. Firefox has the same problem, except it's just MIDI export problems.

This is the same problem for all iOS browsers because Apple doesn't want developers to bypass restrictions on engines.

This is why those problems exist in OS.

This was also originally the problem on Microsoft Edge, but when they moved Chromium it's way better (this is the browser I use. pretty good, huh?)

These browsers are Chromium, therefore working best on OS: https://en.wikipedia.org/wiki/Chromium_(...n_Chromium
