This is a great epub viewer, thanks!
But I have a feature request to make. Could you add an option to turn off display of epub on the browser automatically? There are occasions when I need to download the epub to the harddisk directly instead of viewing it on the browser. Right now I have to disable the addon in order to do that.

This review is for a previous version of the add-on (1.4.0.1). 

Thanks for your review!

In many cases you can already download the file instead of opening it in Firefox: instead of clicking on the link, make a right click and select "Save as". In some cases this doesn't work but as a workaround you could open the file in the first step in Firefox and save it then via EPUBReaders "Save" button to your disk.
I'll put this on the change list, so you will be able to save the file directly to disk in all cases.
