Mozilla Crash Reporter
The Mozilla Crash Reporter is a dialog box that warns you when Firefox closed unexpectedly and lets you submit the crash report to developers for less crashy future Firefox versions. We'll present you its interface and show you how to access your crash reports.
- For suggestions on how to prevent Firefox from crashing, see Firefox crashes - Troubleshoot, prevent and get help fixing crashes.

When Firefox crashes
After Firefox crashes, the Mozilla Crash Reporter window will appear.
Tell Mozilla about this crash so they can fix it: If this box is checked, the Mozilla Crash Reporter will send a summary of the crash to Mozilla. Deselect this box if you don't want to send the report to Mozilla.
: Will open the "Report Contents" window, where you can view the technical details of the crash.
Add a comment (comments are publicly visible): Use this box to add any further information that might be useful to developers trying to find the cause of the crash. The comments you post may be read by anyone.
Include the address of the page I was on: When checked, the information you send to Mozilla will include the website you visited before the crash.
Allow Mozilla to contact me about this report: Check this box if you would be willing to receive emails from the development staff should they need followup information from you about this crash. (You may also receive an email after your crash has been processed, with support information.)
Enter your email address here: If you chose to help our development staff get information and reproduce this crash, provide the email address you wish to be contacted at here.
Quit Firefox: Close the dialog and don't start Firefox again.
Restart Firefox: Start Firefox again. Firefox will give you the option to open the windows and tabs you had open before the crash. If you crash again after choosing to restore your windows and tabs, one of the pages you were on is causing the crash. In this case, choose.
Viewing crash reports

Crash reports are stored in ~/Library/Application Support/Firefox/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 ~/.mozilla/firefox/Crash Reports/
The Crash Reports folder will contain two subfolders: pending and submitted. The submitted folder contains text files for each crash report submitted, with each file containing a crash report ID. For example, a file named bp-031b02bb-26b6-4168-ac0e-2de492090531.txt will contain the following text:
Crash ID: bp-031b02bb-26b6-4168-ac0e-2de492090531
You can go to https://crash-stats.mozilla.com/ and copy the Crash ID into the search field to view the report.
