I completely hid my tabs with custom css and I'll never go back. With something like vimium-c you can switch tabs with vim-like bindings and an fzf-like menu. If you have lots of tabs, the fzf way is way faster to pick out a specific tab than it is to look for it in a tab row (or column). If you have few tabs, you don't even need to see them to know where they are. I'm being very serious. Tabs are bloat. I recommend trying it out if it is something for you.
(edit) On top of that, it looks so clean. You get a bit more space for the actual content (I also hide my url bar, it pops up when you use it). It fits right in with a keyboard focus workflow, you get consistent keybindings across vim and your browser (I use the same keybinds for switching buffers in vim so it feels the same).
Qutebrowser is very cool! Personally I want to use firefox's engine (or at least not something chromium based). Otherwise I would have jumped ship to qute or surf already. Currently my only gripe is that the plugin doesn't work on pdf's and other special pages, which is not an issue on qute.
