About mozregression

mozregression is an interactive regression range finder for Firefox and other Mozilla products. It uses a binary search algorithm for quickly determining a changeset range corresponding to when a problem was introduced.

Currently, mozregression can work with:

• firefox - default
• thunderbird
• fennec (Firefox for Android)
• fenix (Firefox for Android)

To get a feel for how mozregression works, see this video from Pascal Chevrel:
