 	Description: This is a recreation (and better) version of my pseudo-popular Vivaldi vertical tab integration, for tree style tabs in firefox. This is probably the best Tree Style Tabs interface out there.
 	Author: @Drannex42 (https://github.com/drannex42/linux-utils - https://macleodsawyer.com)
 	Notes: This works best with my custom userChrome.css file in the /firefox/ folder - Lots of very cool features built in.
