Mebug

To ensure representativeness, there are five popular, actively maintained software projects from three separate domains, namely desktop (Firefox and Eclipse), web (MediaWiki and Moodle), and mobile (Firefox Android). In addition, one commercial closed source application (Industrial) is included. The proprietary bug tracking system is from a Vancouver-based mobile app development company. The bug reports are filed by their testing team and end-users, and are related to different mobile platforms such as An- droid, Blackberry, iOS, and Windows Phone, as well as their content management platform and backend software.
