Mozilla Crash Reporter TB
The Mozilla Crash Reporter sends your crash report to a collection system, which assigns a crash ID. You will want to post your crash ID(s) in your bug report or support request. Also, Thunderbird developers use this crash report to make future versions of Thunderbird crash less frequently. (The Mozilla Crash Reporter comes up because Thunderbird crashes; it does not cause Thunderbird to crash.)
For suggestions on how to prevent Thunderbird from crashing, see Thunderbird Crashes.

When Thunderbird crashes
After Thunderbird crashes, the Mozilla Crash Reporter window should be displayed where you can supply additional information, then click Quit or Restart to submit the report. Please submit all crashes, including repeats, with your email address so developers can reach you if needed. Also, provide your crash report ID in your support and bug postings.
Tell Mozilla about this crash so they can fix it: If this box is checked, the Mozilla Crash Reporter will send crash data to Mozilla. Uncheck this box if you don't want to send the report.
Details...: Shows some information that will be submitted with crash data. But don't post "details" in support requests - support requests need your crash ID, which is created after submitting your crash report by enabling "Tell Mozilla ..." and then clicking Quit or Restart.

Viewing crash reports
Skip to Viewing reports outside of Thunderbird if you can't start Thunderbird. If you can start Thunderbird, to view your crash reports:
- In Thunderbird, open Troubleshooting Information from the menu, and go to the "Crash Reports" section.
- Crashes are listed by date and time.
- If a crash was successfully submitted to the crash database, the crash report ID is shown, starting with the characters "bp-". In the screenshot below, the report ID is "bp-24b627a1-1416-4c09-a4ab-d7f502100331".
- Numbers which do not start with "bp-" have not been submitted. Click the number to submit the crash report.
- If you are receiving help in a bug or support forum, please give them your crash report ID(s) as a text string, not a screenshot.
- Click on a report ID to view the report. The report lists related bug reports, where you can click on the bug number and offer additional information about your crash in the bug report. If no bug reports are listed, please create one by clicking "Report this bug".
If you don't get a crash report, see If you don't get a crash report described later in this article.
Viewing reports outside of Thunderbird
You can find crash information in the Crash Reports folder on your computer without starting Thunderbird. The folder contains two subfolders, pending and submitted. submitted contains reports that have been submitted to and received by the crash report database. Each file represents one report. pending contains files that have not been received by the crash report database. There are two files for each crash, one is the crash dump, and one is the crash details.
File names in the submitted folder contain crash IDs and these IDs are what a developer may request when investigating a problem related to your crash. The crash report ID is the portion of the file name without the file extension.
- Press +R on the keyboard. A Run dialog will open.
- In the Run dialog, type %APPDATA%\Thunderbird\Crash Reports\ and press Enter.
Crash reports are stored in ~/Library/Thunderbird/Crash Reports/ (show hidden folders, on Mac OS X 10.7 and above, by holding down the Option key while opening the Go menu in Finder and then selecting Library).
Crash reports are stored in ~/.thunderbird/Crash Reports/.
If you don't get a crash report
If you don't get a crash report either because crash reporter failed or it doesn't work with your OS or distribution, you can get a stacktrace by using How to get a stacktrace for a bug report.
