| Mozregression is a python command-line tool for finding a bug's regression range on Firefox nightly builds. Use the [https://wiki.mozilla.org/QA/TDAI/RegressionRangeInstall installation instructions] for your platform. As an example, if you know a bug wasn't present in the nightly for Feb 3 2009, but is present in today's nightly, you can run this command-line:<pre>python regression.py -g 2009-02-03</pre>

| This will download and run a series of nightly builds on a new, clean profile. When a new browser window pops up you can do whatever you need to do to verify the bugs presence in that build, then type 'good' or 'bad' into the prompt depending on whether that nightly is good (bug isn't present) or bad (bug is present), the program will keep on downloading builds depending on your answers. After you've tried enough builds (about 7 for a 100-day initial regression range), you'll see something like this:<pre>Last good nightly: 2009-12-22 First bad nightly: 2009-12-23

| this is good information to paste into a Bugzilla comment. The pushlog url will show you all the code checkins that occurred during the regression range.
