## Description

This is a modern adaptation of the original postMessage-tracker by Frans Rosén. The base logic and functionality still exists (at least it should work the same), although it has been built upon quite a lot.

A LOT of vibing has been going on in here, especially for this port over to Firefox due to repeated requests of the original chrome version over at <a href="https://prod.outgoing.prod.webservices.mozgcp.net/v1/693c05778dcb5d247daac26ee53dd59f81e938ca64428901b8b85ff1c71e1881/https%3A//github.com/Zeetaz/FancyTracker" rel="nofollow">https://github.com/Zeetaz/FancyTracker</a>.
