Fantastic Rated 5 out of 5 stars
This is an amazingly thorough and feature-rich ePub reader--all right inside our beloved Firefox. No need to install some bloated resource-hogging separate application like Adobe Digital Editions. It respects the Digital Rights Management status of the ePub. It even creates an ePub-Catalog where you can see the books you've viewed, complete with Author, Title, Date Added and a drop-down menu to go instantly to the ePubReaders eBook Shop and other ebook sources online. Lets you set bookmarks in the eBook, change font size, navigate Table of Contents in sidebar, save the ePub locally, configure third-party ePub plugins ... The user manual seems to be extensive, well-organized and well-written, with lots of helpful screen shots. Highly recommended.This review is for a previous version of the add-on (18.104.22.168.1-signed).
