I agree that userChrome.css must be modified, but once it is, Firefox is way better for vertical tabs. When you mix in the tree style that is common in the extensions and containers, there is nothing that competes, especially if you work involves managing a large number of accounts for the same few websites, as mine does. It is not uncommon for me to have 10-20 active tabs, and 80+ inactive tabs at any given time. Horizontal tabs can’t compete, and the flat nature of the tabs in Edge certainly turn into a mess quickly.

So what you’re saying is vertical tabs and tab groups are the perfect combination.
I used to use Chrome at work. When Edge added vertical tabs I jumped to that immediately.
Now that IT is allowing FireFox I switched to that with Tree Style Tabs. I am missing the tab groups from Edge, but the tree is worth it.
Yes tree tabs with groups would indeed be perfect.
Sidebery has tab groups and natively supports containers, which is perfect for your use-case. Might as well be TST 2.0.
