Track Packages from the right-click menu.
This extension makes it easier to track a package when the web page or email does not provide you with a link to the shipping company's tracking page. Simply highlight the tracking number, right click, and click "Track Package". It will automatically determine which company's tracking page to go to. This saves at least 4 operations by not going through the company's site or Google, saving time. It also has tracking history and auto-link features.

Does a tracking number not work for you? You may need to use the "Updater" in the add-on's options to update your definitions. Please try this, or email me for more help. It is frustrating when I can't help someone who leaves a bad review because they don't have any contact info.
See Track Package's website for full version history, a FAQ, and more.
