Rated 3 out of 5 stars

I chose this addon because I'm trying to move away from Google apps wherever I can. I like Bamboo so far, but there are a couple of things I dislike. First, TiRANiD's suggestion of having tabs from feeds open in the background. Secondly, I have a couple of feeds that end up with all of their items marked as new whenever the reader scans for new items. I have no idea if there's any current way to put a stop to this, but it's pretty annoying. Also, most of what I follow is webcomics, and the images don't always fit within my browser window, so either automatic resizing for the mouseover popup or a scrollbar as long as the cursor stays within the popup would be great.

This review is for a previous version of the add-on (1.2.1-signed). 

You can use middle click to open links in the background.
In list mode if the popup does not show the entire content you may use the new "view details" iconic button (on the left of the title) to quickly show the full feed item content.

If you still have feeds with all unread items after update with the LAST version of the add-on please send me the feed URL by email at bamboo.feedreader@gmail.com
