Extension:JSBreadCrumbs

The JSBreadCrumbs extension is a simple extension that adds a jQuery-based Javascript file and a CSS file to your wiki's output that will add a trail of navigation bread crumbs below the navigation tabs. The idea is for a simpler history than your back button that only tracks navigation inside of the wiki. Unlike the browser's back button, it will only track GET requests, not POSTs, and will remove duplicate entries from the list.

Supports multiple MediaWiki skins including Vector, MonoBook, Foreground and Chameleon.

Configuration parameters
There are four configuration parameters that may be specified in "LocalSettings.php":

User Preference Options
In addition, there are 8 user preference options. These have default values that can be overridden in LocalSettings.php (see below). Users can then override those default values by visiting  and editing them on the   tab. The user preference options are:

To override the default value of a user preference option, you can put code similar to the code below in your "LocalSettings.php". That is, with this code in "LocalSettings.php", the value of  used for a user if they do not edit the value in   will be 50 rather than the default value of 40 provided in "extension.json".
