Rated 2 out of 5 stars

Agree with earlier remarks about 'view' in tab.
Now it 'jumps' on changing from list to content display
I would find it easier when the feeds are in a Bamboo folder like SAGE does.
I don't know, do not understand, how to make a feeds a favorite

This review is for a previous version of the add-on (1.0.1.1-signed).

To make a feed a favorite just select the feed and click on the "star" button of the menu.

The add-on you talk about is based on Firefox feed management but NOT Bamboo which also works on Thunderbird.
(If you use this module I am surprised that your rating is not higher)

Others points will be ok on the next version. (coming soon)
Thanks for the review.
