Bugzilla is a widely used, free and open source bug tracking system with a web-based interface. It allows users to report bugs and other issues, which are then tracked through their lifecycle as they are investigated and resolved. Many major free and open source software projects use Bugzilla to manage bug reports and enhancements. It provides features like strong security, customization, and localization to support global collaboration.

10. What sorts of things can get
filed as bugs?
Broken code: a traditional bug
feature requests
redesign/rearchitecting requests
your own personal todo items (for things
you don't mind other people seeing)

11. Features (continued)
Strong Security
- Bugzilla runs under Perl's "taint" mode to prevent SQL
Injection, and has a very careful system in place to prevent
Cross-Site Scripting.
Customization
- Everything in Bugzilla is done using templates, from emails to
the user interface. These templates are written in HTML, CSS,
and Java Script so they are easy to edit.
Localization
- Depending on the browser and language a user is connecting
to Bugzilla from, they will be served in their language. This is
great for global open source projects.
