640189 - Occasional Firefox crashes not reported by breakpad

Status: RESOLVED INCOMPLETE

(Firefox :: General, defect)

Description

[Daniel Einspanjer [:dre] [:deinspanjer]]

Filing this for Mark who is a friend and works in the same office as me currently.

He runs Windows 7 Firefox beta and typically has several 
windows open with multiple tabs at any given time.

Since around beta 9, he has suffered from occasional crashes that rarely 
triggered breakpad.  The crash reports that are recorded tend to be 
random and not seemingly correlated.  He has stopped watching Hulu 
through Firefox at this point because he felt that it frequently led to 
Firefox hanging on shutdown which required him to kill the process.  He 
does have some add-ons installed but hasn't done significant customization.

Specifically, he does not run multiple profiles ( -no-remote ) but does 
run multiple windows and doesn't block ads so there is plenty of plug-in 
interaction on all windows.


Would like to know what we can do to deliver some useful information to you guys to triage.

Went to about:crashes and most of the crashes look like they were not submitted? When I get a hang or crash, I almost never see the breakpad dialog to submit a crash report. Here are the ids as listed in the about:crashes page followed by the processed report ids after clicking on them:

Also, Bas asked for video driver details.  I'll check whether there are any updates later today, but for now, I am running this:
NVIDIA GeForce 8800 GT
Provider: NVIDIA 
Driver Date: 7/9/2010
Driver Version: 8.17.12.5896

It's pretty hard to say anything meaningful without seeing a stack trace, we have a wiki doc with instructions on how to get one for crashes like this:

Mark: those reports you just linked were all plugin crash reports, FWIW. (The reason they might not have been submitted is because you just get the sad plugin dialog, and have to click something there to submit them.)

So Mark, if you get another hang, it would be useful to have WinDbg set up and ready so you could attach to the process and get a stack trace before killing it.

If you find a case where you can fairly easily reproduce one of the crashes that doesn't give either a windows or breakpad crash report dialog, then you should run Firefox from WinDbg so you can catch it.

Assuming testcase no longer exists
