It has a built-in function for vertical tabs? I tried to enable them with extensions but they are not great and the horizontal tabs remained which needed css code to take them out.
Also I really like the implementation of profiles in Zen. Firefox has decent groups but I still prefer the Zen implementation and design now.
By profiles in Zen, you mean the workspaces?
Yes correct, I like how you easily see visually in which workspace you are and how you move from one to the other by pressing forward and back mouse buttons.
Oh OK but that's not profiles. Profile switcher would let you have completely different browser settings, extensions and fingerprint. Firefox and forks still have no easy way to switch profiles yet : (
