唯一的问题是无法打开超过一定大小的文件，目前测试下来是90M左右

Nicely implemented interface for epub.js. It has a library for the E-Books (because it doesn't require any permissions to access user data and/or Internet, it cannot directly open the ePub from Pages, the books must be downloaded and opened from the extension's library.) It remembers where each book was open (although there's a bug, it goes back one page every time a book is open, until it reaches the beginning of the chapter.) It could be much better if it had a search tool (Ctrl+F works, of course, but just to find words in the currently viewed page, not in the entire book.) All in all, better than the most popular FF ePub viewers, at least, regarding resources and permissions.

Tried several epub readers and this one is my favourite! Clean interface, easy to use, and some very nice customization options.

比firefox官方推荐的那个epubreader好用的多。

windows上最好用的免费epub阅读器了。唯一的小缺点是颜色设置的地方，没有给出文字提示三栏颜色分别控制哪里，以及如何自定义更换颜色。刚上手的人可能无法正确更换颜色。另外就是打开目录和关闭目录时，文本宽度能否保持不要改变。以及在窗体或目录开关时导致文本缩放时略微感觉卡顿。另外就是缩放时，控制条没有自动保持在可见范围。其他很完美了

Facile et rapide. Très agréable à utiliser.

A clean, simple, fast epub reader. Definitely better than firefox recommended one. hammering the existing few bugs will be nice.

After Microsoft removed epub support from Edge, I was grieving until I met this top-notch add-on. Thank you developer. This is the best epub reader among all epub reader. Even much more better than what was on Microsoft Edge.

Nice looking epub extension. Works as intended.

great

简介实用，有竖屏滚动模式特别好评，功能上还有很多可以增加的，比如不能自定义字体、没法修改版面宽度，不过这两点自己F12改下元素样式就能搞定问题不大。

真正问题比较大的是注释不能点击出现小窗口显示，而是直接跳转到注释，然后再点下注释跳回来，容易打断阅读体验。还有三点不是很重要的说下个人看法，第一就是比较希望能添加一键展开全部目录功能，在一些工具书的检视阅读时会很提高效率；第二就是滚动阅读时在一个章节阅读完后没法滚入下一个章节，需要通过点击目录来完成，如果阅读到一章尾部能出现提示性进入下章的按钮或者快捷键就好了；第三就是希望一些超链接不要跟正文一个颜色，最好也能自定义颜色。

以上是暂时想到的，希望插件越做越好
