How can I stop the "Firefox has stopped working" window from appearing?

Sometimes Firefox actually stops working and "pop-up" window appears with the message "Firefox has stopped working". I have a process that continually monitors FF which is running a GM script 24/7 and when it spots that FF has stopped working it aborts the process and restarts FF. Unfortunately the pop-up window doesn't go away and the old process is still seen in the mix. If I manually click on the stop program button in the window then the new FF process also seems to die. If I close the window using the X button then I have a FF ghost process that won't stop. How can I stop the window from appearing?

Not sure I understand what you are doing or why.

How can you monitor Firefox is continuing to run by using a GM script which itself is running in Firefox ?

Possibly the best you can do is confirm Firefox is running due to some other agent looking at Firefox GM script output. Firefox should run once started and continue until you stop it.

You should try to close Firefox from the menu options not by killing it otherwise it may not shut down properly and you may have trouble restarting it.

What exactly is the WIndow you see is it a Firefox Crash ? If so you should investigate those

I am monitoring the output of the GM script with a separate process.

Occasionally a window pops up which says Firefox has stopped running do you want to restart. 

I haven't found a programmatic way to detect this window and press it's buttons. This can happen any time of the day or night (or weekend) so when my monitor process detects no output from the GM script for a certain period of time then it restarts FF, but the pop-up doesn't go away and neither does the old FF process although the parent.lock is freed so my new FF process runs correctly.

Hi again John,

If the WIndow you see is a Firefox crash then Firefox should by default restart again. There is a pref that may be changed to modify this behaviour

I am not really understanding the purpose of your setup. Ordinarily Firefox should not be crashing, but if it is then perhaps you should look into the reason for that rather than how Firefox is restarted.

It's quite a complicated setup my GM script is about 8000 lines long and runs 24/7. It's extracting data and updating an ORACLE database that I only have access to through a browser based application. I try to be near real-time with the extraction and I then feed our own system to produce notifications of changes to the database as well as statistics and many other things not provided by the original application. My suspicion is that the javascript in the application has bugs and hangs when it gets a delay in the response from the corporate network, but I can't prove that and don't have any access to the application. Anyway at times the application freezes and then my GM script doesn't run because it's event driven on page change. My monitor process can handle that and closes down the application and restarts FF, but occasionally FF produces the pop-up window that I mentioned and then things go a bit strange. I don't want FF to auto-restart for two reasons: 1. I often get the session manager window which requires user input 2. FF is started with a specific user profile, there are several depending on what I want the FF session to do. Auto restart doesn't know which profile to start up with.

This pop-up window is quite new I don't remember ever seeing it before FF28. I can try to take a screen shot next time that it happens but that may be tomorrow or in 2 weeks time I haven't found out how to predict it yet.

Please allow Firefox to crash next time. This will generate a crash report that we can look at and try to find out what the problem is.

When my multiple profile Firefox crashes it restarts with the profile that was in use. As for it having a user input screen on restart the pref browser.sessionstore.max_resumed_crashes can be increased in value and that should prevent that from occurring.

I would be interested in a screenshot as I can not think of a recent change to the popup Windows that gives you a new popup.

Presumably the crashes only occur when the 8k lines GM script is in use. That's going to be beyond my payscale, and possibly out of scope of this forum, but I will tag as escalate and see if HelpDesk staff or anyone else comes up with useful advice You forgot to add 'escalate' for HD to reply. Added! ~m

I did not find anything for your CrashIDs e.g.


Note they are ordinarily prefixed with bp- if they have been submitted.

Ok as soon as it happens again I will send a screenshot. Is it possible for me to resend the dumps?

John48: (John99 should change his username :P)

Usually when Firefox crashes, the Mozilla Crash reporter comes up and presents you with two options (Quit or Restart Opera wait, wha..?Firefox). Either one will submit it to the crash-stats.mozilla.com page but sometimes they don't get submitted for some idiotic reason.

You can see if you have any new crash reports (preferably with bp- prefixed to them) by going to about:crashes in your Address Bar within Firefox.

Something that complicates the issue. My FF profiles are not on a local drive but on a drive attached to a server somewhere in the network. Also firefox.exe is on the same network drive and not the C: drive, this is to overcome the fact that I am not local admin and do not have the correct permissions to install software on the machine. It also gives me the flexibility to run this GM script from any available PC.

more options

But as I said at the beginning. This system runs 24/7 in unattended mode. Therefore nobody sees the Crash reporter and there is nobody around to press its buttons. Secondly I don't want either of these options because I need control over what is happening. If the browser crashes and restarts itself without my monitor process intervening then I get locked out of the application for around 40 minutes. I need a crash reporter that can submit the dump in unattended mode and then exit without quitting or restarting FF.

Thanks for those interesting links. Ideally I would like FF to submit the crash report silently and do nothing else. I need to detect the fact that the GM script has stopped creating output, I need to do a 'graceful degradation' of the application, stop the browser and bring it up again with the correct profile (I have several profiles depending on what I want the GM script to do). So if FF crash reporter comes up with windows asking me to make a choice then it blcks my automated crash detection and recovery.

I had another one of these crashes during the night. You can see here the screenshot of the message.

We're sorry to hear that Firefox is crashing. In order to assist you better, please follow the steps below to provide us crash IDs to help us learn more about your crash.

  1. Enter about:crashes in the Firefox address bar and press Enter. A Submitted Crash Reports list will appear, similar to the one shown below.
  2. Copy the 5 most recent Report IDs that start with bp- and then go back to your forum question and paste that into the "Post a Reply" box.


Thank you for your help!

More information and further troubleshooting steps can be found in the Troubleshoot Firefox crashes (closing or quitting unexpectedly) article.

None of my crash reports start with bp. That's probably because I have crash reporter disabled and that's because it interferes with my auto-restart procedures. Can you please tell me how to manually submit the crash reports?

I think you go to about:crashes, select a report and click Report this Crash.

Sorry much of this is outside of my experience and knowledge.

I marked this question as escalate last week11th. I will ping HelpDesk by PM to see what HelpDesk staff or others can add. It may however be decided that your operation of Firefox as a unattended browser is off topic for this forum and that you would be better asking somewhere else such as Mozilazine.

Idea / Questions

  • Are you able to create the new window whilst Firefox is running attended on your local machine.
  • Set a version and profile of Firefox on A local machine with similar prefs etc where you can observe it directly.
  • I note probably the key salient point is that you say the window you see is new and you can not detect it programatically. Looking at your screenshot I am not sure what is. https://support.cdn.mozilla.net/media/uploads/images/2014-07-15-01-40-52-911af7.png
  • You may have to separate your unattended browser operation and the browser crash troubleshooting investigation. Graceful closedown and predicted behaviour may not be possible after a crash.
  • What happens when you deliberately crash a local observed instance of Firefox ?
    • Do you see the same new popup Window ?
    • What actually is the new popup Window ?
    • I am guessing it could be a tab of a Firefox Window presumably created by your GM script, or something else not an alert generated by Firefox itself.

I have probably already said much of this

Obviously when Firefox Crashes something has gone wrong, and problems may then be expected.

When Firefox closes normally it should have no problem starting with the same profiles the next time, that is what my Firefox normally does. If you start Firefox from a commandline etc. you will have again have no problem deciding exactly which profile of your choice it uses to startup.

If you want crash reports so that you may investigate the cause of the crash you need to let the crash reporter run and set prefs to allow submission of the CrashReports.

Otherwise If you do not submit crash reports you have an alternative option to get a stack trace from the (Normally Windows) OS.

If your crashes result from your use of your 8K lines GM script you yourself need to investigate that and I imagine you will need to commence from some sort of reduced test case where you use a handful of GM script lines to trigger a reproducible crash, and demonstrate that is due to a Firefox bug. (As opposed to performing an operation that would be expected to crash Firefox or being in a situation where Firefox crashes anyway, for some other cause such as Out Of Memory)

Hi, Thank you for your question, this is the Help Desk in response to the escalate tag.

Two things for further action:

  1. The error that you are receiving, does this also happen with local profiles that are not on the Network Drive? and do you have a local security software that may be scanning?
  2. Please try stackoverflow.com with your question for any questions on how to implement a programmatic way to detect this warning/error that Firefox has stopped working.

Suggestions for network drive profiles, though this is not a guaranteed solution to this issue: http://www.novell.com/coolsolutions/t.../3626.html and http://www.experts-exchange.com/Softw.../Q_27587743.html

For further investigation on cause of crash, please post the crash reports and we can take a look at why it may be crashing.

Thank you very much, and we look forward to your reply.
