I want to like it, but every time I try to use it, the button positioning is below the edge of my screen. I really wish it just had simple buttons for 1) save the file to DISK 2) navigate etc. We're SO close, please. Or some kind of non-custom UI which is guaranteed to work despite other extension/other things I have installed. Thanks!

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.

Works good

I Love Firefox

When you try to read from left to right it gets a little wonky. #NotAllBooks

I first tried an extension by this name in Chrome, and it didn't work. Perhaps it was an old version. When I installed this addon in Firefox, it worked very nicely for local .epub files (competitive with other readers). One limitation is that only the arrow keys move between pages, not space bar or page keys or giving a page number.
