ePub Viewer Extension

ePub Reader extension adds a context menu item to the browser link context to open and render *.epub and *.opf files in a browser tab for easy access without the need to install a native software. This extension uses the \"Reader View\" interface which offers three color schemes (light, dark and sepia). The user can change font size and family from the left side panel. It is also possible to view the eBook in full-screen mode. Table of Content is also displayed to let the user jump to a chapter easily.

Notes:
1. This extension stores the current page number and the book URL in the address bar, so if this address is opened in a new tab, the book at the current position will be opened. This is useful to continue reading a book later.

Change Log:
0.1.3:
Load from local *.epub and *.opf files
Display loading percentage.

Vern Brinston (ID: 000000ecfc12f273) Voted 1 ★ - Updated 01/18/2022 Contrary to the description this is a reader only. There is no text to speech and there is no convert to PDF. This guy is a flat out liar!

Chelle “WillowRaven” Campbell (ID: 000000e9441f38b9) Voted 2 ★ - Updated 09/26/2021 Wasn't able to use it. Tried to drag and drop an .epub book in to the window and it comes up with the circle with the line through it - won't load the book. It would be nice if you had a "load from device"/browse option instead of the drag and drop.
