Exploring Firefox Extensions

Gary writes "If you haven't made the switch to Mozilla Firefox it may be because you aren't aware of the great benefits Firefox has over IE. Flexbeta has posted a nice HOWTO guide on Firefox extensions; my favorite is the Target Alert extension which displays a small graphic next to links that are not web pages. For example a mailto: link will display a small envelope, a link to a PDF file will display a small Adobe icon, etc."
