What software do I need to play the Mollom's audio CAPTCHA?
Mollom delivers its audio CAPTCHAs using an Adobe Flash player. To play the audio content, click the link beside the CAPTCHA that says "(verify using audio)" and then click the green "Play" button to hear a CAPTCHA sequence repeated audibly.
Your browser must have a working Adobe Flash extension to load the audio player, and if one is not found, most browsers automatically prompt to download the appropriate extension when Flash content is encountered. If an automatic prompt does not appear, or if you need to reinstall a Flash player on your system, manually download the Flash plugin from http://www.adobe.com/go/getflash.
Note that in some versions of Google Chrome (which uses its own internal Flash player), the green "Play" button is not immediately visible when you click on the link to "(verify using audio)". Clicking on the white space to the left (where the image CAPTCHA was previously) should trigger the audio content, and cause the green "Play" button to appear.
