I'm sorry. It was a personal project, but it became popular. I'll write a short guide in the description.

Opens in a new window parcelsapp.com with your order's tracking code to see where your parcel is.

Add a new link to the merchant's main page to open links in a new tab instead of the current one.

How to use:

• Go to orders
• List all shipped orders
• Hover track order and click on the tracking number

Note: The script doesn't work on the order tracking page
