I want to like it, but every time I try to use it, the button positioning is below the edge of my screen. I really wish it just had simple buttons for 1) save the file to DISK 2) navigate etc. We're SO close, please. Or some kind of non-custom UI which is guaranteed to work despite other extension/other things I have installed. Thanks!

I love this! It was just exactly what i needed, instructions were very clear and easy to read

So simple to download and use! Thankyou Mozilla.

Good

Not very amused with this addon.
Doesn't stay as an App Tab, doesn'nt save reading position and i have to reload the epub every time staring Firefox (Systemstart)

It's a reader all right, but it just opens the book, without an option to download/save it.

That's a massive problem.

Good proggy, fast and small - ecxellent - Thanks
