Good, but needs work Rated 3 out of 5 stars
This is a potentially great add-on, but it needs further work:
* As noted by PCWorld, when printing, it only prints the first page. That's a fairly obvious problem that should have been fixed before release.
* iReader permits selecting a default font family but, so far as I can tell, does not permit selecting font size. Ironically, iReader does permit zooming in or out, but does not permit selecting a default. This also should be an easy fix.
* When scrolling, the text breaks up until scrolling stops rather than scrolling smoothly. Since this does not occur when scrolling within Firefox, it clearly is a problem associated with iReader.
