Hi, It sounds like there might be iframes present in the page which cause your extension to run more than once. You can disable this behavior by setting the "all_frame" attribute to false in your manifest, as described here: http://code.google.com/chrome/extensions/trunk/content_scripts.html#registration
Cheers,
~Arne
