it needs to collapse automatically, otherwise it just wastes a lot of space
If you want collaspable vertical tabs, you should look at using sideberry & this userChrome.css file set: https://github.com/Redundakitties/colorful-minimalist/tree/main
I am using this https://github.com/lucaspar/firefox-vertical-tabs/ ; same idea
In the Nightly version of Firefox only.
You can also wear a hat with the brim sticking straight out to the side and get the same results.
Not opposed to this, but why do I want this?
I suppose many responsive sites have a maximum content width that is admittedly a lot smaller than many displays these days. I guess this lets you use a couple more pixels of vertical space by trading the wasted horizontal space.
If you have lots of tabs up top you can’t see the names, vertical tabs lets you see more/all of the tab titles.
I have been using the tree style tabs add-on for years, it’s amazing for a tab hoarder.
It’s also clearly still in development and doesn’t really work well yet, so while fun, probably not something you’ll want to use yet. It’s not even at the point where reporting bugs makes sense.
