Rated 4 out of 5 stars

Many users don't understand what this program is really about.TrafficLight main function is not to rate sites (that module still needs work and I have it turned off).What makes a difference in this add-on is that it scans sites in real time when you open them (it connects to Bitdefender servers and checks the site against a black list).So, if you want a good site rater use WOT. Then install TraficcLight, disable "Search Result Analyser" if you want (that will leave you with the Phishing Filter and the Malware Filter) and you'll have a very good complement to your security set up.
Remember as well that it is a very recent application, but it's evolving fast.

This review is for a previous version of the add-on (0.1.19).  This user has other reviews of this add-on.
