firefox addons：NoDoFollow https://addons.mozilla.org/zh-CN/firefox/addon/5687?collection_uuid=bc4cc95e-f715-95d6-7e45-7f9e24cc0222
you can also check view resource page(ctrl + U), I think obviously you can look do follow or no follow.
you can check the page source (right click on the page and select view source/page source) and if the link has a rel=nofollow atribute added to it, then it is nofollow. or you can use firefox nofollow plugin nodofollow. if the plugin is installed, when you are browsing FF, you need to right click and select nodofollow. if the link is highlighted in pink, it is nofollow. if blue then its dofollow
Just open your view source (source page) and go through the link there you can see rel="nofollow" attributes. its means that link is nofollow. dofollow is normal link.
Checking the source is cumber some. I would suggest using SEO for firefox addon available from seobook.com
I personally would not worry about it. You need to have a natural link profile, and building only followed links is hardly natural.
You can use Firefox ad dons such as SearchStatus or you can see it manually; means open view source page and check if a link has a rel=â€nofollow†tag added or not.
Just look into the source code of the links, if there's a rel="nofollow" between the <a and the > it's nofollow, if there's nothin, it's dofollow.
check source of link if there is rel="nofollow" in anchor text the link will be no follow. Also there is one mozilla tool bar to check nofollow and dofollow link.
Addons are easier but you can use 'view page source' although this can take time (sifting through all the code)
