This is a small and simple extension, which gives additional customizations for the Tangerinefox theme. The icons and images of the about:home page, the Firefox PDF viewer (PDF.js), the about: page and the about dialog will also appear in the Tangerine look.
Important: The two extensions Tangerinefox about:home and Tangerinefox PDF.js, which came with the Tangerinefox theme package, are obsolete. They are merged in this new extension now. You can uninstall them now.
