you can’t install sites native app
There’s an extension that lets you do this. I use it and it works great.
I don’t think tab groups have been implemented yet
Funny thing is that forced group tabs on Chrome mobile is what made me ditch it.

The PWA app works decent, but, unless I did something wrong, it would open links in itself instead of my main Firefox window which wasn’t what I’d want normally.
I still use it, but it’s definitely not as nice as I’d want it to be.
Definitely one of those things that’s minor and I can look past though.
