Liferea

[4] The lead programmer of Liferea, Lars Windolf, who is German, pronounces the name of the software [lifəreja].

Additionally, the user can configure an external browser (e.g. Firefox, Web, Konqueror) with which to open links.

It supports a number of different feed formats including RSS/RDF, CDF, Atom, OCS, and OPML, many of which its contemporaries cannot.

By enabling a filtering preference, all previously read headlines of the folder can be hidden.

[6] Liferea can synchronize with online services such as Tiny Tiny RSS and The Old Reader to allow reading news feeds from multiple devices.
