how to see nonfollow links on the browser?>

how to configure your browser to display nofollow links differently from regular links and how do i check to make sure the comments on blogs are do follow?

If you use firefox then you can get a plugin. Google nofollow firefox plugin (it comes up as no**************** in the rightclick menu once you have it). When you activate it (right mouse click option) all the links in a page become highlighted. Red means nofollow, purple = follow.

This will then let you know what blogs' links are in that regard.

or you can use seomoz toolbar / seoquake for firefox or crome - the 2 best seo plugins for browsers in my opinion. there are several greasemonkey script too for nofollow highlighting too.
