Visit your site the way your users might
Ever wondered how a differently-abled person might experience a web site? This extension can give you a taste. With it, you can disable mouse use, convert to grayscale, disable images, and even apply blur, allowing you to experience a page as other users might.
Great for manually testing and empathy-building, this is not a diagnostic tool that will report specific flaws, but rather a lens through which to view the web.
