Thank you for this Add-on. I'm gonna need it when Mozilla turns off the dynamic bookmarks. But I've found some differences. Perhaps there is a way to integrate the following points.

- Dynamic bookmarks of Firefox show more entries (if available). I tried it with the feed of orf.at (Austrias most popular news site)
- When I have read a bookmark the icon changes. That's very useful.
- The description field is automatically filled in the dynamic bookmarks (irrelevant but just saying)

Btw. if you need a translator for German I can help you.
