For sites that are very dynamic in regards to their contents, it may sometimes be helpful to keep track of all the links you have previously visited so that you do not visit them again. This can be useful on eBay if you are browsing a particular search every now and then, on image hosting sites, message boards, Twitter, when you search on the Internet, and when you are visiting any other site to which new contents are added to regularly.

Visited is a great extension for the Firefox web browser that lets you mark all visited links in the browser in a color of your choosing. The feature is enabled by default and you will notice that it highlights all visited links in orange after you have installed the add-on.

This may not be the best color, and if you do not like it open the preferences of the extension to modify the visited link color here to a more suitable color.

The extension supports several hotkeys that toggle its functionality:

  • Alt-V to highlight visited links or display them in the default way.
  • Alt-Shift-V to pick a random color for visited links.
  • Ctrl-Alt-Shift-V to highlight image borders or to display them in the default way.

The last hotkey highlights visited image links on the page as well, something that is not done by default. This can be useful if you hang out on image boards for example so that you can avoid clicking on image thumbnails that you have already clicked on before.

The extension furthermore highlights image links automatically in a specific color that you can change in the extension preferences as well.

You may notice that highlighting link colors is not something that you may want on all sites that you visit. It makes for instance not sense to do so on the WordPress admin dashboard as those links are visited regularly anyway.

You can exclude sites so that the extension ignores them. You need to load about:config?filter=extensions.visited.except in the browser, double-click on the preference and add all domains that you want excluded in a comma separated list here.


Once you add a domain to the list, its link colors are no longer highlighted in the browser.

It would probably make more sense in my opinion to use a whitelist instead of a blacklist for that, so that the extension would only work on whitelisted sites if you want to limit its reach.

    Many Comments on The Mozilla FF addon page
    report the same warning:
    “After some time this addon stops working…”.

    So, unfortunately, avoid this addon.

    BUT to achive the same objective,
    you can puy this in your usercontent.css:
    a:visited { color:#990099 !important; }

    Same color effect, w/o any addon.
    Hope this helps others.

      Yes, but it does not work on website where default link color darker than Firefox’s visited link color.
