Nodofollow FireFox Add-On

I have just found the new plugin for FireFox.
Created by ZaharyFox has a simple name NoDoFollow, and if active
shows directly in the browser regular links in blue color, and links with attribute nofollow in pink.
The former versions of plugin had a problem with recognising complex attributes,
they showed rel=' external nofollow ' as the normal link ( blue color ) but the present version works correctly.
The nice tool for fast search for 'DoFollow' blogs.
