If i am viewing the website , i want to know whether that site is using Do-follow or no-follow links ....
I would recommend to use the SEO for Firefox plugin. It will highlight all no follow links in red, so you can tell easily just by looking. Just Google "Seo for Firefox" and it will be the top result. It is a free download also. Hope that helps Here is also a link to the plug-in: http://tools.seobook.com/firefox/seo-for-firefox.html
I have the same tool - but come to find out the nofollow attribute within the anchor tag never really stopped googlebots from following. Personally, I think there was a little trickery done by G just to cut down on spam.
I'm using chrome and it has the same thing in some of their extensions. It will highlight the link in red if it's nofollow. Just search on google for %browsername% SEO (extension/plugin) and you should find one.
