Tips: You can always ask ChatGPT or other AI to generate the script.
This Extension's activation is based on the current page you're seeing only, to make the extension to auto activate each time a link is opened. See further below.
1) Create a Folder (name it whatever you want, it will be where you store the scripts
2) Create 2 files:
manifest.json &
background.js
