Attention

TYPO3 v6 has reached its end-of-life April 18th, 2017 and is not maintained by the community anymore. Looking for a stable version? Use the version switch on the top left.

There is no further ELTS support. It is strongly recommended updating your project.

The Extension Manager (EM)

Extensions are managed from the Extension Manager inside TYPO3 by "admin" users. The module is located at "Admin tools > Ext Manager" and offers a menu with options to see loaded extensions (those that are installed or activated), available extensions on the server and the possibility to import extensions from online resources, typically the TER (TYPO3 Extension Repository) located at typo3.org.

The Extension Manager (up to TYPO3 4.5)

Interface of the Extension Manager (up to TYPO3 4.5) showing the list of available extensions.

The Extension Manager (from TYPO3 4.5 to TYPO3 4.7)

Interface of the Extension Manager (from TYPO3 4.5 to TYPO3 4.7) showing all available extensions.

The interface is really easy to use. You just click the +/- icon to the left of an extension in order to install it and follow the instructions.
