Like i said earliier, im a web dev, and that’s a list of web standards, and a comparison which browser has implemented which spec.
You literally said you don’t understand them, so maybe brush up on the subject you are discussing instead of telling others how things are?
I’m not defending anything, just providing info and saying why I use what I use.
If a browser is missing official standards features, then the browser is objectively lagging behind. Yes, the web devs are at fault for using things that lack wider support, but that comes down to many factors such as having the time and money to implement things in a more complex manner to support more browsers. That’s not always feasible or possible if a certain core feature lets us save hours or days.
In a perfect world the UI would be customizable to the extent that I feel at home and don’t need to unlearn and relearn patterns ingrained in my brain. For me those patterns are very relevant as I work in the field and every time the tools force me to spend more time working around them instead of with them, lead to loss of efficiency.
Extension support exists in some Chrome based browsers, too. Kiwi Browser also comes to mind.
Remote debugging is also important to me, and even though you can install Chrome dev tools in Firefox, it doesn’t work with remote debugging.
