Latest Firefox Mobile nightly builds, pushed out today for testing have enabled the Mozilla Crash Reporter provided by Breakpad. Breakpad crash reporting tool (developed by Google engineers) together with Socorro (a server to accept and process Breakpad crash reports) offer a common crash reporting system for Firefox 3, Thunderbird 3, SeaMonkey 2 and now Firefox Mobile “Fennec” for Nokia N900.
When Firefox Mobile crashes, you’ll see the screenshot above (taken from Fennec developer Mark Finkle’s Weblog). The crash reports you send to Mozilla end up at the Mozilla Crash Reports web site, where you can track them. You can also use about:crashes to view all the crash reports generated on your device.
