Bugzilla instance of bug tracking system
Bugzilla is a web-based general-purpose bug tracking system and testing tool originally developed and used by the Mozilla project, and licensed under the Mozilla Public License.
Released as open-source software by Netscape Communications in 1998, it has been adopted by a variety of organizations for use as a bug tracking system for both free and open-source software and proprietary projects and products. Bugzilla is used, among others, by the Mozilla Foundation, WebKit, Linux kernel, FreeBSD, KDE, Apache, Eclipse and LibreOffice. Red Hat uses it, but is gradually migrating its product to use Jira. It is also self-hosting.
