Rated 4 out of 5 stars

I started looking for a Firefox plugin that would allow me to preview any and all shortened URLs due to a recent phishing attack on twitter. This is the only plugin that seems to do it, and does it well. I just set it up as a white list (default deny), and have been adding rules for redirects I know are safe.

This review is for a previous version of the add-on (1.2.4).
