A new (to me at least) toolbar is available. The Compete Toolbar seems nice. It seems to be trying to see its Trust Scores (can you trust this site) and Deal (which tells you about deals on teh site you are visiting). Both seem decent. Trust I would bet will leave off a bunch that are trustworthy but so what. If it indicates tusted sites that seems worthwhile. I like the site profiles feature.
Other popular toolbars: Google, Alexa, Yahoo.
