mozregression

Introduction

mozregression is an interactive regression range finder for Mozilla nightly and inbound builds. It uses a binary search algorithm for quickly determining a changeset range corresponding to when a problem was introduced. It is widely use by Mozilla developers and other community members to help find regressions.

To get a feel for how mozregression works, see the video on codefirefox.com: http://codefirefox.com/video/mozregression
