Rated 4 out of 5 stars

I was very happy when I discovered this excellent epub reader since there is no plugin for Calibre which I use to manage all my ebooks. Now I was very disappointed to find out EpubReader does make a copy in my Firefox Profile of every local epub I open with it. For this only reason I have uninstall it . Should you create an option for not making copies of local epub (which Calibre has already copied), I'd be glad to reinstall it and recommend it because it's really excellent.

This review is for a previous version of the add-on (1.4.2.1).
