This section contains information for end-users of Bugzilla. There is a Bugzilla test installation, called Landfill, which you are welcome to play with (if it's up). However, not all of the Bugzilla installations there will necessarily have all Bugzilla features enabled, and different installations run different versions, so some things may not quite work as this document describes.
Frequently Asked Questions (FAQ) are available and answered on wiki.mozilla.org. They may cover some questions you have which are left unanswered.
