did not expect to see ADOM here, but it makes sense. It's probably the oldest still maintained game mentioned here.

It looks like it does, but unfortunately it doesn't.

Liftoff has "Use in app browser", but all it changes is whether the link is opened in a full Chrome window, or a "Running in Chrome" window.

It doesn't let you pick which browser you want to use.

I use Chrome for serious things (e-commerce, work, etc) and Firefox for everything else.

It gives an extra layer of protection if a vulnerability is able to steal cross site login details.
