Add-on summary
Allows you to quickly navigate to or copy the canonical version of the URL you're on, if available.
What? In a nutshell, a canonical link is the "clean" or official version of a webpage URL.
Example of a non-canonical URL:
https://www.amazon.com/Apple-iPhone-GSM-Unlocked-5-8/dp/B075QMZH2L/ref=sr_1_3?s=wireless&ie=UTF8&qid=1516789917&sr=1-3&keywords=iphone+x
Example of a canonical URL:
https://www.amazon.com/Apple-iPhone-GSM-Unlocked-5-8/dp/B075QMZH2L
See the difference? One has tracking info, tags, and queries, which are generally only useful for the site owner, where the cleaner, more human-readable version is better for use with: bookmarking, linking to from a website or social media, marketing materials, and search engines.
