Mozilla used to allow you to disable the crash reports that were sent when one of their applications died on you. But if you're running the latest Mozilla programs, they have changed their crash reporting system to use something called Breakpad. And it doesn't give you a box to check so that you can skip sending crash reports in the future. This affects all Mozilla apps -- Firefox, Thunderbird, SeaMonkey, and the Suite.

There is a way to set things up so that the crash reports can be disabled, but it's a little more effort than just checking a box. You need to find the application.ini for each application that you want to turn off Breakpad for. This file lives i the installation directory and you can find a list of the directory locations by Application/OS here: http://kb.mozillazine.org/Installation_directory. Or you can use the search mechanism on your computer to find the location of the file.

Once you find the application.ini, you need to edit it. Look for the section list this:

[Crash Reporter]
Enabled=1

You want to change the value of Enabled from 1 to 0. Once the edit is made, save the file.

From then on when you start the application, if a crash occurs, the Breakpad crash reporter should be skipped.
