"Breakpad" is a new crash reporting system from Mozilla which is a core part of Mozilla Firefox 3.x,
Thunderbird 3.x and
SeaMonkey 2.x products. It was developed to replace the old "Quality Feedback Agent" aka "Talkback" present in previous versions.
Whenever any of these 3 Mozilla products crashes, Mozilla crash reporter shows a window asking you to send the crash report to Mozilla servers and allows you to quit or restart the application:

There was an option to disable "Quality Feedback Agent" aka Talkback in earlier versions but Mozilla didn't provide any option to disable this new crash reporter "Breakpad".
If you want to disable this crash reporter, you can do it by simply editing an INI file:
1. Open My computer and goto the installation directory of the application:
Mozilla Firefox: %programfiles%\Mozilla Firefox
Thunderbird: %programfiles%\
Mozilla Thunderbird
SeaMonkey: %programfiles%\
mozilla.org\SeaMonkey
Here "%programfiles%" stands for "C:\Program Files" folder. Replace C: with your system drive letter where Windows is installed.
2. Now look for "application.ini" file and open it in Wordpad.
3. At the end of the file, you'll see following lines:
[Crash Reporter]
Enabled=1
ServerURL=
https://crash-reports.mozilla.com/submit
4. Simply change the value of Enabled to 0 as following:
[Crash Reporter]
Enabled=0
ServerURL=
https://crash-reports.mozilla.com/submit
5. Save the file and now you'll no longer see the Crash reporter window.
