I'm looking for a way to change the color of the links I already visited (videos & channels) on Youtube without having to install and addon/extension.
I set toolkit.legacyUserProfileCustomizations.stylesheets to true.
I created the chrome folder with a userContent.css
I put the following code into the .css
Code: Select all
@-moz-document domain(youtube.com) {
a:visited { color: purple!important;
}
}
What I'm doing wrong here?
