I can't go on the pages in the opened book.

Doesn’t work

good tool but drag and drop option for file opening would be nice to avoid time intensive searching in open dialog. Flaws with fullscreen mode (white empty areas at bottom with dark background). Read aloud addon does not work properly with this reader. (might be a Read aloud problem)

Works good

Simply does not add a button to open already existing epub files. Something must be broken. Doesn't appear when I try to customize my buttons, either.

This is good for those who can't find a good standalone ePub reader and it monitored by Mozilla. I like dark mode with white text which is easy on the eyes. Furthermore, Read Aloud can read from it. Although great, I think an update is overdue. I would like a history of files previously opened.

Can not open downloaded file

Perfect... EXCEPT for the fact it doesn't work in fullscreen

unintuitive but it works
