So simple to download and use! Thankyou Mozilla.

Good

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.
