I disagree. When done right, tab management can make or break the browser. Extensions can't do all the things a native UI can. See Arc for example. Aside from amazing tab management story that made it hugely popular, it was a pretty uninspiring Chrome clone overall.

I'm currently using Zen since it's the closest thing to Arc with full MV2 support. If native Firefox with the new UI can do what Arc/Zen can do, I'll switch to it probably.
