Yggdrasil Switcher от FSKY

Yggdrasil Switcher is a browser extension that helps you find alternative versions of websites hosted on the Yggdrasil network. It alerts you when a Yggdrasil-compatible version of the site is available, allowing for a seamless transition to the decentralized web.

It looks for the Yggdrasil-Location header on websites to alert the user if the website is available over Yggdrasil. For more information on the Yggdrasil-Location header, see the specification page.
