These extensions (tools) are easily found, for example a search for "nofollow firefox" or "nofollow chrome" will give you alternatives. I have an extension for Chrome, and any link that is nofollow is shown with a line through it.

I am rather surprised at your question given that in another thread you say of yourself "I am experience search engine optimizer"?
Yes I know about the extensions and add-one that you mentioned in this post. I try to use this to find dofollow blog. Can you suggest me any software or tool that exact tell about this problem??
