If you exclusively use vertical tabs (either with CSS or another way), how is it? Did you miss horizontal tabs at all?
I’m trying to switch to Floorp right now from Firefox, where I have both the regular horizontal tabs, and a flat vertical list with the Tree Style Tab extension. I use the later a lot, and while I could keep this setup in Floorp, I like that the vertical tabs can be native instead of using TST. However, it just feels weird to not have horizontal tabs. I think I might miss seeing a bunch of my tab titles at a glance with it, but I have to use it more and see how I feel.
Is Floorp the only option for Firefox for removing horizontal tabs?
I like the idea of vertical tabs, but only if I can get rid of the horizontal bar and free up that extra screen space.
Ideally I'd have both horizontal and vertical tabs, since its easier to glance horizontal tabs, but I think I'd get used to just horizontal after awhile.
