Web Feed Subscription Button от capjamesg

This extension finds RSS, Atom, ActivityStreams 2, and h-feeds on a web page.

If one is found, the extension icon will show. When clicked, the extension icon will take you to your feed reader with the feed URL.

This extension can be configured to work with any feed reader that has a prefix feed URL (i.e. https://example.com/subscribe?url=), like Feedly, Newsblur, and Artemis.

If you open an XML document in your browser, this extension will automatically redirect you to your feed reader so you can subscribe to the feed. This prevents you from seeing an XML document on sites that link directly to XML documents for their RSS feeds.
