With this style, Flickr will highlight the links that you have already visited.

This style improves page navigation and element focus, for Flickr, which does not display the pages you have already visited in a separate color.
This makes Flickr a lot more usable, so you do not go to pages you have already been to (visual history).

* Based upon Roblesolido@userstyles's Link: Visited hyperlinks with opacity effect.
