Mozilla is working on bringing vertical tabs to the Firefox web browser, and you can try the feature right now, if you want.
I'd rather have an official way to move the tabs back to underneath the address bar that doesn't involve modifying the userchrome file
Never heard of that idea. Sounds like a slightly lazier way to do it, but I respect it. Could be easier for accessibility reasons I suppose.
Getting vertical tabs and hiding the original tab row is the only thing I have to mess with the userchrome file for myself, so this getting baked in will help me skip an extension setup and file edit every time I set it up on a new device. Or freshly setup device.
