FurAffinity Favs par quizzl

I consistently find many of my eventual favorite artists through the favorites of other users. FA is largely designed to facilitate this kind of exploration, but not being able to subscribe to the favorites by themselves makes this otherwise excellent way to explore the content on the site clunky and time-consuming.

This extension manages a subscription list to other users' favorites, loads them when the extension is [re]loaded and shows new ones since the last session.

See all the features in action in this demo/quickstart video. Source code on GitHub. Details of how this extension rate-limits itself and leaves your data untouched are also found on the GitHub repo README.
