Right-Click Package Tracker от csaba_vs

This extension adds a "Track package" option to your right-click menu whenever you highlight text. It automatically detects the tracking number format and launches the correct official portal in a new tab:

Austrian Post: Matches exact 22-digit numbers.
UPS: Detects standard alphanumeric 1Z formats.
FedEx: Handles 12, 15, or 20-digit shipping codes.
All other formats: Drops back to an all-in-one universal lookup via ParcelsApp.

Works locally on your machine, handles basic cleanup of spaces, dashes and colons, and collects absolutely zero user data.
