There is a new way to detect rel=nofollow tag using the firefox browser, Detecting this tag helps in catching cheating webmasters using this tag in their directories and link exchanges,

rel=nofollow tag can be highlighted in firefox by adding a simple line to the main CSS file ( usercontent.css ) which powers the appearance of the web pages in firefox browser,

we have to find the path of the usercontent.css file and add a simple line so that the rel=nofollow link appears in a different colour,

For Windows XP / windows 2000 users:

C:\Documents and Settings\[User Name]\Application Data\Mozilla\Firefox\Profiles\hmgpxvac.default\chrome

hmgpxvac can be anything on your system,

For PCs using Windows 98 / ME:

C:\WINDOWS\Application Data\Mozilla\Firefox\Profiles\hmgpxvac.default.default\chrome

Open up your new userContent.css file and add the following line:

a[rel~="nofollow"] { border: thin dashed firebrick! important; background-color: rgb(255, 200, 200)! important; } save the file,

if above code is used firefox will automatically highlight links in red,

You can highlight links in internet explorer too refer the attached for it,
