ALL MY NEWSFEEDS HAVE DISAPPEARED FROM ONE DAY TO ANOTHER!!! Rated 1 out of 5 stars

I daily used NewsFox without having to face any major problem. However this morning, all my newsfeeds completely disappeared. My newsfeed folders are totally empty! All that without any valid reason. I restarted several times Firefox 3.6.8 but no newsfeed reappeared at all! How can that happen with a recommended add-on as "Newsfox"?! I am very disappointed and will not recommend this add-on anymore at all!

This review is for a previous version of the add-on (1.0.5). 

Some local problem?

Have you tried to check the folder where NewsFox stores feeds' info? It performs backups, so it is very difficult to lose feeds with NewsFox.
