This is a most excellent place for technology news and articles.
The TreeStyleTab extension for Firefox has added vertical tabs for a decade
Yes, but you have to have a custom user.js file or whatever to remove the tabs on top.
Ok, so do that once and you're done. :)
It should be an option in the UI though.
I have been running vertical tabs for a while now and it's broken about 3 times, once every few months. Currently, I've had no min/maximise/close buttons for about a week because I can't be bothered to fix it. Far from "one and done".
