Webmaster Extension for FireFox is a FireFox add-on that has a lot of interesting uses.  It displays information on every outgoing link on a website.  First it shows the pagerank, quality (trust rank) of the domain, and then projected traffic based upon compete.com’s rating.  What won’t show up are javascript links, internal links to the same site, and https links.  Below you can see a picture of it in action.

You won’t even notice it’s installed other than seeing a small W2 icon at the bottom right of your browser.  Simply click on that Webmaster icon and the pagerank suddenly appears.  On my own site, I found one of the links in my blogroll had gone from a PR 4 to a PR 1!  Sorry, but it had to go.  I don’t like to link to spammy sites penalized by Google.

How is this plugin useful?  Say you have a blog and want to make some comments on other blogs in your niche.  Google your keywords and then activate the plugin.  You will see the pagerank of all the links on the page.  Same goes for your own site.  Go to your WordPress comment page and click the icon for the plugin.  Now you can see the page rank of everyone who ever commented on your blog.  

Issues:  I am running Vista on Firefox 3 and had a small issue with the plugin.  I only saw the page rank and not the trusted icons or Compete icons.  This is fine because the page rank is what I’m most interested in.  As you can see below, the most important feature of the plugin works perfectly.  Here is an example of the blogroll from Evilwoobie.com.

I can quickly see if her blog links to real sites, or is a link farm for spam.  Hmm, seems OK except for that “Hot Guys” link.  Wonder how that got there?  Go ahead and check out the Webmaster Extension for FireFox.
