Rated 4 out of 5 stars

This used to be my RSS reader but after it was discontinued, I switched to Inoreader (website) + Inoreader Companion (add-on) and couldn't be happier. With a couple of adjustments, it's basically the same experience for me, plus this setup is available for all browsers. You just configure the add-on's icon so that it takes you straight to the website and you're good to go.
