Yes, I’m a big fan of Gurren Lagann, which led me to create this theme. The theme is essentially designed for a clean interface. Unfortunately, that is the place where the main images are usually placed so that they are not too affected by the tabs, the URL bar, or Firefox's base buttons. I can only recommend that you manually clean up any additional buttons you don't use, keeping only the essential ones to minimize obstruction of the image. Thanks for your comment.
