Wow. I rly hope it will be included soon as possible. It's a main reason why I need to use Vivaldi for meetings! Hope that audio will be shared too

We need it for sure, because it's very comfortable for eyes in the evening and night.

I believe that vertical tabs it's important for the browser. Because realisation in Vivaldi for example are good. Or you can use tree style tab addon + function to hide horizontal ones. I believe that developer will be happy to be a part of Mozilla.
