Be a part of the Firefox 3 world record attempt over the next day-or-so! I fully endorse "The Fox" (as indicated by the 'endorsement' panel of this blog) and find it makes for an excellent browsing experience. Download it, and if you're on a PC use it and give Internet Explorer a swift kick in the jodhpurs. If the record attempt has finished, you can still find it here.
Also, you can download a certificate to show you were a part of the record attempt. An excellent companion to a wall full of academic and philanthropic certificates, diplomas and degrees.
