The way tree style tabs worked after they broke it was never very good. Floorp is what to use if you wanted side tabs on Firefox.
That said I still went back to Vivaldi after trying to use Floorp because of stupid little ux issues like pinned tabs not being protected from closing, and broken session saving.
The issue is that because they broke the UI customization that allowed for it all the extensions are just a kludge to add a panel to the side without actually getting rid of the top tabs.
Its honestly the only reason i use brave and edge over Firefox. Can fully commit to FF now.

Sidebery is a very good implementation of the vertical tab panel

Yes, but you have to have a custom user.js file or whatever to remove the tabs on top.
