Not the OP, but I've never found anything faster than the Livemarks plugin for quickly scanning headlines from all of your favorite sites with a quick mouseover in your browser's bookmark toolbar.

Livemarks (or the Chrome/Vivaldi equivalent 'Foxish live RSS') was released after Firefox killed off their Live Bookmarks feature a year or so ago.
