The extension works with category 1 and 2.

After borrowing a book, two new buttons, "Quality" and "Download", appear under the book viewer alongside the "Favorite" button.

On rare occasions where the buttons did not appear upon page loaded, click the extension button on browser toolbar to open settings page and click "Show Buttons".
