hover - CSS Link: Why only "Visited" is not working

Question

My Firefox is not showing the color for visited links:

a:link {
  color: blue;
  text-decoration: none;
}

a:visited {
  color: green;
  text-decoration: none;
}

a:hover {
  color: cyan;
  text-decoration: underline;
}

a:active {
  color: yellow;
  text-decoration: underline;
}

Answer 1

It is related on the browser's chronic: This option must be activated, to see different colors! It's not really logical, as in an active session the pages visited can be seen by Menu > Chronic, even if that option is INactiv. Anyway, now it works!
