Dead simple, no-frills Rated 4 out of 5 stars

This is exactly what it says, an ultra-lightweight RSS extension. Do not expect drag-and-drop capabilities. Do expect to set it up yourself. But it's dead-simple, fast, and does the job. I like that it doesn't require any sign-in, account registration, etc. It just reads RSS feeds, that's it.

The only feature I really wish it had was the ability to check for updates in my subscribed feeds, but I recognize how much more involved that would be compared to the current no-frills feature set.

This review is for a previous version of the add-on (1.10.1). 

It now sets itself up for the most part, has drag and drop subscription organization and does show which feeds have unread updates. Thanks to your suggestion!
