WordPress Plugin: Frame Buster

I’ve written my first WordPress plugin. It’s called Frame Buster. This technique is also called a frame breaker or frame busting. It places some JavaScript in the heading of all pages that will prevent the page from appearing in someone else’s frame. This happened to one of my sites a couple of years ago and it was done to steal the site’s content. I did not like it. It should be noted that it will only work if the client browser has JavaScript enabled.
