I’d like to ask the same thing. The main things I want from my browser are for it to be a good browser. Fast and secure with excellent tab and bookmark management capabilities. Anything else except maybe ad blocking is extraneous.

I understand that a lot of people live in their browsers, but for web apps I’d rather split them out into “installed” PWAs and have them benefit from system app/window management facilities than have them clog up my browser’s tabs.
