Rated 3 out of 5 stars

It says compatible with 3.6 and installing goes fine with FF however upon opening of the chm file, I get garbled ascii characters. Upon checking it seems that the add-on was only updated for linux and not for windows. Darn. It really is a good and useful add-on to read ebooks and the only one that exists in doing this kind of stuff. To the developer or someone kind enough please update this! It has a lot of potential!
