How to Disable Mozilla Crash Reporter aka “Breakpad” in Firefox, Thunderbird and SeaMonkey

"Breakpad" is a new crash reporting system from Mozilla which is a core part of Mozilla Firefox, Thunderbird and SeaMonkey programs. It was developed to replace the old "Quality Feedback Agent" aka "Talkback" present in older 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 go to the installation directory of the application:

Mozilla Firefox: %programfiles%\Mozilla Firefox
Thunderbird: %programfiles%\Mozilla Thunderbird
SeaMonkey: %programfiles%\\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]

4. Simply change the value of Enabled to 0 as following:

[Crash Reporter]

5. Save the file and now you'll no longer see the Crash reporter window.


In newer Firefox versions, you can disable Crash Reporter using Firefox Preferences or Options window. Just open Firefox Options, go to Advanced section, click on Data Choices tab and then uncheck "Enable Crash Reporter" option.

  • If you don't report the crash to Mozilla ..they don't restore your tabs.

    If you do ..they restore ..This is so not good

    I still like firefox but who knows

  • why all the trouble. just go to the program directory in windows and delete the crash reporter and the dialogue will not appear again.

    really got myself damn mad when the dialogue box keep showing (past 2 months) whenever I close firefox.

    all recommended solutions online are cr@p - won't solve the problem.

    so, the very basic thing to do, just delete the software (reporter) itself. and it's gone. peace on earth again.


  • IT doesn't work ,Do you have another way to repair?

  • Not only does the firefox application send a "CRASH REPORT", it also fills up the C - Drive rapidly causing the system to hang. It actually consumed something like about 50 Gb in less than a few months.

    See this under the path -
    USERS/(User Name)/AppData/Roaming/Crash Reports/pending.

    Firstly, if you wish to disable the "Crash Report" then see -

    Ensure that you purge the folder under the "Pending" or "Submitted" periodically if you are yet using the "CRASH REPORTING".

  • Like so many others, I hate this crash reporter. Im sick and tired of been "engaged by the machine" to do something, its really bad when some new feature is introduced, and automatically activated, so us poor users have to figure out how to un-do it. Either this generation of new programmers is clueless, or their managers.

  • I have just had to empty the pending crash report folder of 94,973 files created in the last two days.
    Only 2,3Gb unlike the 50Gb BALA CHANDER had, but enough to cause problems, and Firefox hasn't even been very crashy, and hasn't been asking me to submit reports.
    It seems your crash reporter is a problem itself.

  • I tried disabling it in the options of Firefox and sometimes, it will still bring up
    the crash reporter dialog box. You can probably do it with the .ini file mentioned
    but that is the hard way. Just go to: C:\Program Files\Mozilla Firefox and locate
    "crashreporter.exe" ... cut it and put someplace else (where you can find it again
    if you want to) ... Now Firefox will not be able to bring it up, as it does not know
    where to find the executable file.
