Search Toolbar for Firefox is a really great extension for FireFox that makes displaying search engine related stats very very comfortable…

For every site you visit using Firefox or Mozilla, SearchStatus lets you view its Google PageRank, Google Category, Alexa popularity ranking, Alexa incoming links, Alexa related links and backward links from Google, Yahoo! and MSN - all in one place.

This combined search-related information means you can view not only the link importance of a site (according to Google), but also its traffic importance (according to Alexa), so providing a balanced view of site efficacy.

And you don't need any sort of Internet Explorer with tons of different toolbars installed. Install it today!
