NativeBook 作者： Vierkas

Credit to 0727hana for her Book PDF Viewer who serve as based, the whole project has been remake from almost scratch by me it had a lot user friendly feature and more feature, i added so much thing to make it easy to implement in daily life that it started to make me modify almost everything until i told myself it could be publish because maybe someone would like it too.

NativeBook replaces Firefox's default scrolling PDF display with a two page, flip able book view, complete with a real page turn animation.
How it works: Navigate to any PDF, or a link that opens one inline, and it opens automatically in the book viewer.

Controls:
1) Arrow keys, the on screen buttons, or clicking the page edges to turn pages
2) Double click a page to flip back or forward
3) Ctrl or Cmd plus/minus, or Ctrl/Cmd plus scroll, to zoom, and double click the percentage to reset it
4) Fullscreen toggle
5) A button to turn off book view for a specific PDF and fall back to Firefox's normal viewer at any time
