1420767 - Crashes goes unreported

Status: RESOLVED INCOMPLETE

(Toolkit :: Crash Reporting, defect)

Description

[Jon Loldrup]

User Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/62.0.3202.94 Safari/537.36

Steps to reproduce:

Start firefox 57 on win7 64bit


Actual results:

My fancy new Firefox 57 crashes a few seconds after starting. Every time. The crash reporter doesn't catch it, so you'll never know the details!! (Muahaha!!)
I guess that's the core of this issue: the crash reporter doesn't report on these crashes.


Expected results:

Working normally

There are a few cases where our crash machinery is unable to generate the crash dump. We could debug this using WER if you could do the following:

1) In the Windows registry create the HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Windows Error Reporting\LocalDumps key and leave it empty
2) Use Firefox until it crashes
3) Once Firefox has crashed dismiss the debugger window you're presented and go into %LOCALAPPDATA%\CrashDumps (e.g. C:\Users\<name>\AppData\Local|CrashDumps) you should find a file called firefox.exe.<number>.dmp there
4) Send me the .dmp file via e-mail, do not attach it to the bug since it might contain sensitive information

If something went wrong and no .dmp file was generated try again but this time launch firefox manually via cmd.exe with the MOZ_CRASHREPORTER_DISABLE=1 variable set, e.g.:

set MOZ_CRASHREPORTER_DISABLE=1
cd "C:\Program Files\Mozilla Firefox\" # Or the correct path to Firefox installation directory
firefox.exe

Once you're done you can delete the LocalDumps registry key you created, this will prevent WER from gathering more minidumps. See this page for more information on this:

I'd love to do this, but since I need this computer in working order, I long ago reinstalled Firefox, which caused the problem to go away.
I will remember this method if I should experience future unreported crashes from Firefox.

OK, thanks I'll be closing this bug then.
