See what’s behind the site with mouse X-ray glasses.

Mozilla X-Ray Goggles, a very small tool that lets you view and edit the code behind any web page. Unfortunately, they shut it down a few years ago and since then I have been recommending that people use Chrome’s Inspect tool to see the code behind a web page. In fact, I even included it in my weekly newsletter this week. This week I discovered that offers its own X-Ray Goggles tool for viewing and editing code at the back of the page.’s X-Ray Goggles tool allows you to view the code behind any web page and change that code so that you can display anything instead of the original text and images. After making changes you can publish a local copy of the web page. In this short video, I demonstrate how’s X-Ray Goggles tool works.

Applications for education’s X-Ray Goggles give students a great way to see how webpage code works.

As I mentioned in the video, you can use X-Ray Goggles to turn an article on the web into a satirical story. Then print the page and try to help your students identify the satirical elements of the story.
