Tree Style Tabs is one of my favourite browser extensions of all time, but it's alreody pretty broken on Firefox 42, and apparently it depends quite a bit on reaching into the browser's UI code and rewritiing chunks of it. I will be very sad if it breaks completely, but not very surprised.
when I lose Tree Style Tabs, I will be deeply saddened and how I browse will be greatly changed.

As is mentioned on the WebExtensions page, they want to add APIs enabling things like that.
