Special styling for NoFollow links

This is a great way to look at a website and see what links are tagged as NoFollow, meaning the link will not count as a vote in Google. This is a must on your website if you don't want to be penalized for linking to know spammer sites or what Google calls a 'Bad neighborhood'. With this little Firefox hack you can quickly see what links have been tagged - for reviewing your website or any other.
