Most browsers except Chrome have some sort of vertical tabs support.
- Safari (Mac) has a vertical tabs, but a very confusing UI, mixing Profiles, Windows and Tab Groups (only 1 level).
- Edge has Workspaces and Vertical Tabs, along with Groups (only 1 level).
- Chrome does not have vertical tabs and has 1 level groups
- Vivaldi has vertical tabs and groups, not sure how many levels of grouping.
- Firefox has Containers and Vertical Tabs (today), but for best results you still need something like Tab Stash, Sideberry or TST.
- Orion Browser (Mac) has the best UI imho and allows for grouping tabs at as many levels as you want, but you cannot have proper "folders", only nested tabs.
- Arc gets everything right, in my opinion, but I do not specially care much for the candy UI.
