{"version":"1.0","type":"rich","title":"Firebug : go to canvas!","description":"This example shows how to redirect Firebug’s command-line context to Facebook’s canvas iframe, enabling direct JavaScript and jQuery selector access from the console. The code executes a single Firebug API call, `cd($$(\".canvas_iframe_util\")[0].contentWindow)`, which uses `$$` to select the first iframe with the class `canvas_iframe_util` and then switches the console’s working window to that iframe’s content. It relies on Firebug’s built-in command-line functions rather than external libraries. The snippet is derived from a Stack Overflow answer and also includes a bookmarklet version for one-click activation.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-1069440?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
