User:Dickvl/TabVisited

In Firefox 3.6 and above it is no longer possible to use the selected attribute to style unvisited and visited tabs with code in userChrome.css and only the selected tab gets a selected="true" attribute. In previous Firefox 3 and 3.5 versions visited tabs get a selected="false" attribute, but that attribute was removed to fix buggy behavior [1], [2].

TabVisited

I have attached an extension TabVisited to bug 487242 to add a visited attribute to tabs that have been visited that can be used until bug 487242 gets fixed.
Tabs that haven't been visited do not have that attribute. The currently selected tab has a selected and a visited attribute.
See comment #c0 [3] (Description) for some coding examples.
You can drop the extensions XPI file in the %AppData%\Mozilla\extensions\{ec8030f7-c20a-464f-9b0e-13a3a9e97384} folder (Linux: ~/.mozilla/extensions/{ec8030f7-c20a-464f-9b0e-13a3a9e97384}) to install the extension for all profiles, including nightly Minefield and Namoroka builds. The extension will be installed on the next start of Firefox [4]

Here are some versions of TabVisited that you can try out. Version 1.1 only adds the visited attribute, so you need to add code to userChrome.css to see visited tabs different. Versions 2.0 and 2.5 have CSS code embedded and work without adding code to userChrome.css. Version 2.5 only sets the text color and not the background color. All three versions work in Firefox 3 and SeaMonkey 2, only tested with the default theme and without other extensions that modify the tab bar.

TabVisited 1.1

Copy and paste the full DATA code in the location bar and save the file as tabvisited-1.1-fx-sm.xpi (Apr 13 2011)
You can install the extension via File > Open File or by dragging the file in a Firefox window.
The maxVersion for Firefox is set to 4.*. This version works in SeaMonkey 2 as well.
