I know this is old news by now, but I was not sure how to activate vertical tabs on all of my browsers. It certainly is not obvious, so I wanted to include the instructions here in case anyone else wants to try it out.
Type about:config into the address bar of Firefox. You’ll be greeted with a warning that you are accessing advanced settings - click “Accept the Risk and Continue.” Search for the boolean preference sidebar.verticalTabs and set to true. That’s it! Enjoy your vertical Tabs!
Oh neat!!
Nice, wheres my tab groups?
There is still no built-in solution for nested/tree-like groups, but for creating simple groups Ctrl+N has served me for many years.
I personally prefer Sidebery, but glad they’re finally putting this feature in as a standard feature
Nice! I’ve been running the nightly for this, looking forward to switching back to regular Firefox.
I like it better than the horizontal tabs, but it’s still got nothing on the Tree Style Tabs extension. With that you can group tabs together, collapse trees, close trees, etc. Makes it much easier to keep things organized
Wow, I had no idea this was already built in! Thank you!
I wonder why this feature is “Obscured” like this, maybe it’s still in beta?
There’s an additional option I have set to true, and not sure what else it provides, but it’s: sidebar.revamp
It feels strange, but also better than scrolling through a line of horizontal tabs?
The only downside is, at least on macOS, the title bar is now only fragile from a small area. Not a big deal.
