@Gargron except when Google decides to artificially slow down it's websites on alternative browsers.
(For context, Google is adding 5 second timeouts for no reason to youtube when you're using Firefox)

From someone on X:

YouTube has started to artificially slow down video load times for Firefox users using the following piece of code:

setTimeout(function() { c(); a.resolve(1) }, 5E3);
5E3 being 5000ms, or simply put 5 seconds.
