masquerade
Description

Allows you to browse the site as another user (to see what they see) and then quickly switch back again.  A general Drupal recommendation is to create test accounts for each of your roles, so this is useful for testing them.  (As per notes, don't use it for anonymous access, just log out.)  Replacement for 'Switch User'.
