Almost perfect Rated 4 out of 5 stars

Light, fast, unobtrusive, and now works on the latest Firefox and Seamonkey. Only quibble is images in remotely stored books sometimes don't get completely rendered -- the top part of the image will show, and the rest will be blank. Otherwise, perfect for my needs.
