Use sidebar tabs. Most websites don't use the full width of your screen. So, it makes total sense to put tabs in the sidebar, instead of them taking up valuable vertical screen state.
it's such a no-brainer, I'm surprised it's not a first-class feature in the main browsers (I'm aware that it is built in or default in a number of niche browsers).
Its one of those things like dark mode, where power users strongly request it for decades, yet corporations push back against it every time. And much the same as dark mode, I predict that all the same corporations will suddenly have a change of heart the second Apple starts implementing it.
