This page contains an iframe and a form field that’s set to “No.” If the page in the iframe loads it starts up a script that sets the field value to “Yes.” Purpose of the test is to find out whether a browser (currently) supports iframes.
Firefox honours my request once I start up a new window. I do not know how to disable iframes in Chrome or Safari. Instructions for the other browsers are below.
The problem is that if I disable iframes in IE9 or Opera, it still loads the iframe and executes the script. And yes, I tried restarting them: no luck.
What? The? F?
I assume I don’t understand something, but ... well ... I don’t understand what I don’t understand.
