The Bugzilla defect tracking system, aka Bug-Tracking System, allows individuals or groups of developers to keep track of outstanding bugs in their product effectively.
Use Bugzilla for systems administration, deployment management, chip design and development problem tracking (both pre-and-post fabrication), software and hardware bug tracking and IT support queues.
Bugzilla can track bugs and code changes, help you communicate with teammates, submit and review patches, manage quality assurance (QA) and more.
