Bugzilla is a vigorous, featureful, and mature bug-tracking system or defect-tracking system that allows teams of developers to maintain track of unsettled bugs, issues, problems, enhancement, and other change requests in their products with effectiveness. Organizations are now turning to Bugzilla as it offers appropriate workflow management, custom fields, and bug visibility control.

Features:

Advanced Search Proficiencies: Bugzilla provides two types of search in which the first includes a basic Google-like bug search that is very simple for new users and searches the full text of a bug. The next is a very advanced search where you can create any search that you want, including time-based searches.

Controlled e-mail notifications by user preferences: You can get an e-mail about any change made in Bugzilla, and the type of notifications that you get on bugs is completely controlled by your personal user preferences.

Bug Lists in Multiple Formats (Atom, iCal and so on): While searching for the bugs, you can get the results in many formats rather than just the basic HTML layout. Bug lists are available in Atom and they are also available in iCalender format. If you are utilizing the time-tracking features of Bugzilla, then you can see where your bugs fit into your calendar. In addition, there are even more formats available, like long, printable report format, CSV format, and other XML formats as well.

Automatic Duplicate Bug Detection: Bugzilla has the calibre to automatically look for similar bugs in the system and enable the user to add themselves to the CC list of one of those bugs rather than filing a new one.
