If you want to implement visited links, do the following:
Copy the following files from: C:\Program Files\mozilla.org\Mozilla\components
appcomps.dll
mork.dll
to here: C:\Program Files\K-Meleon\components
Follow the instructions to create a user.js file posted here:
http://kmeleon.sourceforge.net/docs/custompref.php
and add the following line:
user_pref("browser.visited_color", "#RRGGBB");
Where RRGGBB equals the RGB Hex code for your visited link color. The following would create "red" visited links:
user_pref("browser.visited_color", "#FF0000");
