Features & Capabilities

Feed Preview is a Firefox extension that detects RSS and Atom feeds directly in the browser's URL bar and renders live previews of these feeds.

Key features include extensive support for various feed formats such as RSS 1 (0.9, 1.0), RSS 2 (0.91 to 2.0), and Atom (0.3, 2.0), including obscure specifications. It handles different character sets and uses content sniffing techniques to detect feeds served with XML or RDF content types.

For security, HTML content is sandboxed and sanitized, ensuring safe browsing. It preserves the original feed URL with no redirects, allowing

User Reviews

The add-on is praised for restoring RSS/Atom support, enabling easy previewing/subscription, reliability, simplicity, and direct XML viewing. Recurrent drawbacks include UI/icon visibility problems, missing dark mode, limited customization, occasional compatibility issues on specific Firefox versions, and missing layout/sorting options. Overall, it delivers essential RSS functionality with some polish and feature gaps noted by users.

Missing dark mode/dark theme support and related visibility improvements
Limited customization options (very few settings and cannot remove the top subscribe button)
Inconsistent compatibility on some Firefox versions (not working on certain builds)
Lacks layout and sorting options mentioned by some users

Is Feed Preview Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Feed Preview requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

Feed Preview has earned a fairly good reputation and likely can be trusted.
