Created attachment 633771 [details] testcase The attached testcase sets the color of a ':visited' link to red and the background color to yellow. However, only the text color is applied. Fails: Firefox 14, Chrome Works as expected: Firefox 3.6.28, Opera 12

This is expected behavior due to http://dbaron.org/mozilla/visited-privacy In particular, you're using a solid color for a:visited and a transparent background for unvisited links. The relevant part of the document linked above is: If the relevant link is visited, it returns a color whose R (red), G (green), and B (blue) components come from the second style context (the style-if-visited) but whose A (alpha) component comes from the first. And the unvisited style has an alpha of 0, so you get a transparent background. Which is to say, you should be explicitly specifying backgrounds for unvisited links if you want links to have backgrounds...

OK, thanks. I wasn't aware of that particular aspect of the :visited history leak fix. As you say, it works if the unvisited link has an explicit (non-transparent) background color set.
Yeah... unfortunately, different alpha values for the two colors are subject to timing attacks, hence the restriction here.
