Add Book to Goodreads

Detects books on web pages and provides quick access to add them to your Goodreads shelves. It works on book-related pages across the web, including Amazon, Google Books, publisher sites, and many others. Since the extension works across all websites to detect book information, it requires broad permissions including "Your data on all websites" and "Your tabs and browsing activity".
