I used vertical tabs when Firefox was Netscape.

I used OmniWeb.

Currently Firefox is the only browser that I can get an addon to provide vertical tabs. IUt is called Tree Style Tab

Off the top of my head, Edge and Vivaldi have vertical tabs built-in.

I know that's not the benchmark in this comment chain, but Tree Style Tabs can actually do ... trees (who would've guessed?). Plain vertical tabs are fairly crippled in comparison.

Edge can do groups, but there are only two levels.

Ah yes I forgot Vivaldi - which I did use but it just leaked memory even worse than Firefox - running on macOS
