Sage (Mozilla Firefox extension)

Sage was a lightweight RSS and atom feed aggregator extension for the Mozilla Firefox web browser. The extension was developed by Peter Andrews and Erik Arvidsson.

Sage won the "Most Innovative" award in Mozilla's 2006 "Extend Firefox" competition.

Although as of 2021 the official website is still online, the links to the actual extension on Mozilla Add-ons are not working anymore. Among the alternative aggregator extensions there is one that aims to replace the original Sage, both in name ("Sage-Like") and functionality.
