Erinome RSS di Erinome

This is an almost direct port of "Smart RSS" extension made by Martin Kadlec for Opera browser, except for a few modifications:

• Desktop notifications when feeds are updated;
• Per feed option to choose whether its unread item count should be included into the badge counter;
• An option whether to show only unread items or all items when opening the reader;
• Misc changes in code and some tweaks to default option values.

...And, for sure, a possibility to run it under Firefox.
