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

dobrý pár kodů na 5 pracovních dní kvůli přetížení a zneužití sítí a proti neoprávněnému zažalování

nice

It works nicely for me :). Thank you to the developers!
