I’m trying to install this [extension](https://addons.mozilla.org/extensions/moreinfo.php?application=firefox&category=Popular&numpg=10&id=35) for firefox 1.0.3 (I’m not sure the number, but it’s the latest version), but when I click on the Install Now button, nothing happens except for the Install Now pop-up window. How do I go about installing this extension?

Thanks!
