I have a bookmarklet that sets text-decoration: line-through on visited links so I can easliy spot what links I've already visited in sites that do not distinguish them with a different colour.

Firefox 4 has removed support for most visual clues for visited links and my bookmark is useless.

What are my alternatives to highlight visited links?

NoSquint offers several tweaks to make sites easier to look at, including custom link settings. It can also do this on a per site basis.

Looks like an option, I've try it out. Thank you. – Álvaro González Mar 26 '11 at 18:10

You might also consider Stylish.

Then to do what you want, right click the S, choose "write new style" ... then "blank style"... then paste the following:

@namespace url(;

a:visited { text-decoration: line-through !important; }

And that should do it.

The add-on looks nice and I will try it but I'm not sure your sample style will this work. The problem is that Firefox only supports color for visited links, not text-decoration or even background-color. – Álvaro González Mar 26 '11 at 20:44
maybe that's an old firefox. I actually added that style to see it worked before pasting it. It definitely works on 3.6.16 with the newest stylish. I think you'll find stylish is fun, it can actually modify the firefox UI itself, at least parts of it, as well as the sites. – CreeDorofl Mar 27 '11 at 2:19
It's a feature from Firefox 4:… – Álvaro González Mar 27 '11 at 12:39
oh, geez, I had no idea. So it's not working, even with !important? That's an awkward change... a browser that refuses to obey your css 'for your own safety'. They should make it an option, not just force it. – CreeDorofl Mar 27 '11 at 15:04
