Firefox Add-ons へようこそ。
To celebrate this exceptional service, we’ve developed a Firefox addon which makes using this service a breeze. After installing this addon, you will have a new context menu item labeled "Shorten with mcaf.ee" when you right click on the page or any links in the page. Selecting this menu item will then display the shortened url and copy it to your clipboard for easy pasting into email, chat, or other corrsepondance. The shortened mcaf.ee link will help others know the link you post is secure.
This extension uses the mcaf.ee service which utilizes McAfee’s Global Threat Intelligence information. The mcaf.ee service allows users to create short URLs, which are checked against McAfee’s GTI databases prior to being shown to the end user – no more rogue short links (http://mcaf.ee/b1d069) on Twitter going to malware sites.
