SearchStatus is a toolbar extension for Firefox and Mozilla that allows you to see how any and every website in the world is performing. It displays Google Pagerank and Alexa Score anywhere on the browser along with some basic SEO tools such as fast keyword density analyzer, keyword/nofollow highlighting, backward/related links, Alexa info and few more.
The SearchStatus Mozilla/Mozilla Firefox extension appears unobtrusively at the bottom of the browser on the status bar. If you choose to view backward links for a particular page, they open in new tabs in the same browser window. Disable the automatic Google and Alexa queries and they fold away from view.
Earlier I used Google Toolbar to check pagerank, But i think this One is Best. And this one is Best Tool to All Bloggers.
