Free Webmaster Resources: SEO AddOns for Firefox
Add SEO Power to Firefox with two free addons.

My searches have been missing something since the live PageRank addon became incompatible. It feels like forever. After a bit of searching I found a great addon with live google PageRank and so much more.

SearchStatus for Firefox has an impressive bag of features. Choose where in your browser to display live Google PageRank and Alexa rank. Highlight NoFollow links on the page. Theres a keyword density analyzer and backward/related links. Also includes a link to show indexed pages for Google, Yahoo and MS Live shows you all of the pages on your site, or any site that have been indexed.

SEO Quake has been a popular free webmaster resource for a while, becuase it has stood the test of time. Gives a quick SEO snapshot for your keyword searches. When you’re searching for keywords, get a quick overview of your competitors Page Rank, number of pages indexed, number of links pointing to the page (for google, yahoo and MSN) Plus Digg, and Technorati history and more. Toggle it on and off from the bottom of your firefox browser for easy access.
