NOT intuitive. One would think that that you could scroll by mouse-wheel, or search for keywords. Nope.

This add-on is a little bit wonky. It allows you to adjust font qualities, mostly; you can set up a dark mode, mostly; it remembers where you were in a EPUB, only if you set a bookmark. Nor does it have a library setting, convenient if you keep your ebooks in one place. Also, if you switch full-screen mode on or off, you will see that the reader does not adjust accordingly.

But it does read EPUBs at least as well as another wonky reader (Nook), so I am happy to cut it some slack and grant it five stars.

My initial frustration was relieved when I learned (RTFM) that there is a toolbar button to open locally stored epubs, making my reading MUCH easier and more enjoyable. Five star rating gladly granted.

It's great but it lacks of a dark mode

I think it's a really neat addon! However, whenever I do want to download an EPUB (which isnt too often) I don't have the choice to choose to download it. Also, sometimes it just doesn't load what I'm trying to read.

Extremely basic.
No page numbers, no settings, cant even scroll the pages using a mouse.
