This page is a tracking document for handling and following topcrashes on the trunk.

Info on weekly status meetings for tracking crashes and improvements to the crash reporting system is at http://wiki.mozilla.org/Breakpad/Status_Meetings

If you find an extension or plugin that is the source of a crash consider filing a blocklist request - http://wiki.mozilla.org/Blocklisting

Current topcrashes being tracked 3.1b2

Current topcrashes being tracked 3.1b1

Summary

7 Nov 2008 - Fix for #1 landed in b2. Potential fix for #2, #4, #7, and #8 (maybe #11) landed for b2. Some contrast applies from previous update. Also had a potential fix land for #10 and #15 for b2.

2 Nov 2008 - Top crashes are spread mostly between imagelib (#1), JS (#2, #4, #7, #8), and widget code (Windows: #5, #6 + Mac: #11, #19). Only one clear external crash in the top 10, caused by Norton. This contrasts the top crash list for Firefox 3.0.3 where 6/10 are from external factors.

What do I do?

So, someone CCed you to a topcrash bug and asked for your help. What should you do?

There are several steps that developers and QA need to go through to help fix a crash. As a developer, we're specifically asking that you comment in the bug when you've completed all the steps and specifically state which steps you completed.
