There is a firefox addon that will do that for you. You just right click to turn it on or off. It's very good and easy to use. You can get it here: https://addons.mozilla.org/en-US/firefox/addon/5687 Just so you know, pink means nofollow and blue means dofollow. When I first started using it that wasn't made clear to me.. so I thought I'd save you the trouble.
After you install it you have to restart firefox. Then to use it, just right click on a website page. You will see NoDoFollow in the menu that pops up...click on NoDoFollow and it will turn it on. You do the same thing when you want to turn it off. Additionally, you can do the same thing in the Tools menu at the top of firefox.
I suggest you to install seoquake plugin in your firefox and set (line-through nofollow links) or install searchstatus plugin in your firefox and set (highlight nofollow links) to identify nofollow links. Visit social bookmarking site and check for the referring links. If it is highlighted or line-through, then it is nofollow.
Maybe, you should understand what is dofollow and nofollow first. Actually, you don't need any add on or plugin to check a link is dofollow or nofollow. All you need is to select the social bookmarking site and check the link that it refers to original post. If you can see and rel="nofollow" or external nofollow tag added on that link, than it is nofollow.
