Tool to inject javascript into any website.
First, you need to have the Tampermonkey or Violentmonkey extension. After that you can use which ever method you'd like.
Go to Greasyfork and download the script. This should automatically install it and it should be ready.
Go to your Tampermonkey dashboard and create a new script. After that copy the code from main.js. Do not remove @updateURL and @downloadURL unless you want to manually update this script.
