MediaWiki extensions extend the functionality of MediaWiki in some way.
All extensions are currently in the process of being moved to MediaWiki documentation wiki.
Do not add new extensions to meta.wikimedia.org — go to Manual:Extensions on MediaWiki wiki instead!
This category only contains extensions that have not yet been transferred. In this interim period you will need to consult both this list and the equivalent category on MediaWiki wiki. Sorry for this inconvenience. (More details.)
