Did you know that it is possible to override the way a website is displayed by default in Firefox. This can be useful for instance if a webmaster decided to use CSS code to remove the underline of links, change the color for links that open in new windows or display additional information for certain file type downloads.
The first thing that you need to do is locate or create the file usercontent.css in your Mozilla Firefox profile directory. It can usually be located in %appdata%\Mozilla\Firefox\Profiles\
