User Reviews
its hard to find an eBook reader you like as a visually impaired person, owing to the lack of them. This extension is nearly all that I want though, and the layout isn't bad either. I only wish there was a history of your recently opened books. I also like how it automatically puts you on the page you were on when you open a book, as opposed to putting you at the start of the book
