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

ok

Хорошее расширение, но последнее обновление было давно, и оно не улучшается

The add-on looks and controls great. I had two problems with it:

⦁ It doesn't hyphenate words, which, with justified texts, leaves wide gaps. I know that the problem may be not with the add-on but with the document's CSS not including hyphenation preset. On my desktop and smartphone readers text is hyphenated, so I guess it depends on the reader apps too.🤷🏻‍♂️

⦁ It failed to load images. It may be because the images are vector (.svg). If I click on them and hit "Open image in a new tab", the image loads. I haven't tried replacing .svg's with raster images, but I assume the add-on has no problems with them.

Einfach gehaltenes Reader Programm. Ohne grosse Stellschrauben. Starten, ebub-Datei aussuchen und lesen.

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

Works well

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)
