FA Favs is an open-source extension available for Chrome and Firefox that allows users to subscribe to the favorites of FurAffinity users. This extension opens as a new tab and pulls favorites and thumbnails from a subscription list that you can build on the extension's user interface.

One of the best features of FA Favs is its ability to help users discover new artists. By exploring the favorites of other users, you can easily find new artists whose work you may enjoy. However, one limitation of the extension is that you cannot subscribe to individual favorites, which can hinder the exploration process.

FA Favs is an excellent tool for anyone looking to expand their artistic horizons on FurAffinity. The extension is open-source, ensuring transparency and allowing users to contribute to its development. Additionally, the GitHub repository provides details on how the extension rate-limits itself and ensures the privacy of user data.
