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!

Edit: You may also need to set sidebar.revamp to true if it is not already/automatically set.

I personally prefer Sidebery, but glad they're finally putting this feature in as a standard feature

Sideberry is good, but you end up with tabs in both places. This option allows you to reclaim the vertical space without need for messing with the chrome css stuff.
