EPUBReader FireFox Addon

If you read a lot of non-DRMed ePub books that you find on the Internet, EPUBReader, a Firefox addon that works with Windows, Mac and Linux may be of interest to you. It allows you to read ePub books inline in the browser, rather than having to download them.

Seems like a novel idea, although I'm not sure I wouldn't rather download them (in case the source disappears online), and I still greatly prefer reading in a standalone reading device. That said, the price is right!
