When trying to preview a book in google, I receive the notification 'Website will not allow Firefox to display the page'. I read the page that explains what to do, and tried to open the page in another window, it would only be a tiny picture. If I try to left click the 'preview' button to open in another tab, there isn't an option for that. I can't take a screenshot of it because the left click goes away when I try. I understand that the block is a safety measure, but it's really annoying and I literally can't use firefox to preview books.
