Feed Preview is a Firefox Addon which indicates the availability of RSS or Atom feeds in the browser's URL bar and renders a previews of feeds.

Feed Preview has the following combination of features which are unique in combination and set it apart from similar feed previewing addons:

  • Extensive feed format support: robust parser which handles the RSS 1 (0.9, 1.0), RSS 2 (0.91, 0.92, 0.93, 0.94, 2.0), and Atom (0.3, 2.0) feed families including obscure features, supports non-UTF-8 character sets, and uses content sniffing to detect feeds served with XML or RDF content types
  • Media files: support for enclosed media files which can be downloaded from the preview page
  • Subscription support: allows subscribing to feeds using user-configurable web-based feed readers and ships with presets for frequently used services and integrates with addon feed readers
  • Secure: HTML content/summaries are displayed in sandboxed iframes, all other elements are sanitized
  • Preserves the feed URL: the preview is generated via stream filters before it hits the rendering engine, there are no redirects and the "View Source" function works as expected
  • Modern design: Follows the Photon design guidelines and integrates seamlessly with Firefox
  • Open source: published under the MPL 2.0
  • Internationalization: the code is fully internationalized, user submitted translations are welcome

  • Excellent implementation
  • Does what it says and does it well
  • Works well with FreshRSS
  • Excellent
  • Does exactly what I need: adds back RSS/ATOM support to Firefox
  • Works perfectly
  • It restores the support for RSS and even more. Just perfect. It should be a recommended extension.
  • One suggestion, the tab icon is hard to see in a dark theme. Please provide an icon for the dark mode.
  • Doesn't work at all anymore (FF 94.0.1), no icon is ever shown
  • Very few options and can't remove the subscribe button at the top
  • Wish it had a dark mode/theme. Absolute shame Mozilla removed this functionality natively.
