We should get some QAing around this to help CovenantEyes reproduce the issue, or to understand if we've done anything to tickle this crash.

As part of my inquiry in Comment 1, I asked for a test account since they don't seem to have any trial accounts according to: http://www.covenanteyes.com/services/pricing/
I received an email back from them this evening with a promo code. I will create an account tomorrow and report back.
I created a promo account using Accountability Monthly filter. They have three choices of filters. I installed it and have been running FF 12 B2 but so far have not generated any crashes.
I have now tried different testing scenarios on two different Win 7 machines with Covenant eyes installed running 12b2 and so far have not generated any crashes.  I also tested with some of the addons found in the manual reports (https://crash-analysis.mozilla.com/crash_analysis/20120328/20120328_Firefox_12.0-interesting-addons.txt.gz).

If you look at the uptime data for both signatures there is a bit of a pattern if a longer uptime followed by a shorter uptime. Maybe I have to wait this crash out a bit.

I guess the next step would be try reaching out to Covenant eyes to see if anyone there has been able to reproduce it. I can try responding to the customer service rep that emailed me and see if there is a dev contact there we could work with.

That would be great. Please do so.
Mail sent requesting a dev contact on their side.
I did hit this crash on my Win 7 Sony Vaio today, https://crash-stats.mozilla.com/report/index/bp-0e957831-a21c-4d7b-b9fe-efb862120329.

At the time of the crash I had just clicked a link to download Adobe Flash from http://get.adobe.com/flashplayer/?promoid=BUIGP. Let's see if I can try to more reliably reproduce it.
Any luck reproducing this, Marcia?
(In reply to Anthony Hughes, Mozilla QA (irc: ashughes) from comment #10)
> Any luck reproducing this, Marcia?

Sorry, just noticed the timestamp was from today, not yesterday. I'm not trying to rush you :)
Alex and I talked about getting this in a record and replay to see if there is a way to get any more information. I have to find out if bent still has a machine set up equipped to do this.

During my testing I managed to repro another time but there doesn't seem to be a pattern to the crashes.
Okay, I think I have better STR here after playing around with this a bit more.

STR:
1. Log into Covenant Eyes
2. Load netflix.com.
3. Covenant eyes tries to block the URL so I enter my Covenant eyes user name and password and allow the site to load
4. I enter my Netflix user name and password and then I crash.
5. Subsequent visits to the Netflix site result in a crash.

So it would seen from this testing that after I have "allowed" a site that Covenant Eyes has blocked, subsequent visits to that site seem to result in a crash.

Given the above STR, can we help Brian find a regression window?

Brian requested I try to reproduce the crash using Firefox 11 - using Mozilla/5.0 (Windows NT 6.1; WOW64; rv:11.0) Gecko/20100101 Firefox/11.0 I have not been able to reproduce the crash that I am hitting consistently with the 12 beta on the same machine.

I can check to make sure that this started in the first 12 beta since I think the build I am testing with is Beta 2.

Marcia/Anthony - in the channel meeting we discussed finding a smaller regression window than some time in FF12. Can we get that for Brian as well?
Marcia had told me a couple of days ago that she was able to trace the regression down between 11.0-final and 12.0b1. I advised her to check the mozilla-central 12.0a1 Nightlies to try to track the regression range. Unfortunately I do not have access to the hardware so I cannot assist.

Marcia, were you able to make any progress on this?
The Sony Vaio I was testing on blue screened, so as soon as can get that machine up and running I will retest this.
Turns out hunting down an exact regression range for this bug will be a bit difficult due to the fact that sometimes the browser does not crash right away when I add the filter. I also have to spend time finding sites which will invoke the Covenant eyes filter in order to apply it.

During my testing I still have never been able to crash using Firefox 11. Using the same profile, Firefox 12 latest beta seems to crash fairly easily and if I try to session restore then the browser continually will crash.

I started looking at builds back to 20111220 and so far the only one that has crashed in the range between Firefox 11 and 12 is 20120115.
What is the best way to query all the changes that were made between Firefox 11 RTM and the 20120115 build?

https://hg.mozilla.org/mozilla-central/pushloghtml?startdate=2011-12-20&enddate=2012-01-15

or

hg log --date 2011-12-20 to 2012-01-15

should do the trick. Would it make sense to hook up the crashing case to a debugger?
This is no longer a top crash for recent FF12 betas - Brian will still look into this in case it explodes post-release in the same way it did after FF12 landed on beta. We're specifically looking to figure out where the bug lies (Firefox or CovenantEyes).

I've also asked Kev if we have any contacts at CovenantEyes that Brian can work with, since he strongly suspects this is a 3rd party issue after performing code inspection.

I have had a ton of crashes lately after upgrading to FF12. Any ETA on a solution to this?

Comment 26

6 years ago
I am experiencing spontaneous crashes of FF12.  It will crash while nothing is being done on the computer so I don't think it is the same 'bug' as this but I know how you hate new bugs being reported when there are others already reporting them so I'm posting here first.  I think 'Wes' and I might be experiencing the same thing.

I have followed the suggestions and updated both Windows(XP Pro) and also run in 'safe mode' with no improvement.  Please help as this is more than annoying.

Thanks,
Rob

Wes and Rob, you should disable ConvenantEyes and contact its support site to get it fixed.
The only solution Mozilla could do is to blocklist this DLL so that it disables ConvenantEyes for every users.

Comment 28

I'm pretty sure my problem has nothing to do with 'CoventEyes' as I don't know what that is and I'm pretty sure I don't have it.  I guess this is not the correct place for my post but it was the most recent and Wes's comment sounded more like my issue.

Sorry for the confusion.

Thanks for your help on this.  I'm learning as I go here.  It seems this is clearly  a different issue: 
https://crash-stats.mozilla.com/report/index/7b7d3139-ba01-45a0-8616-ed1782120428

https://crash-stats.mozilla.com/report/index/59564c93-2708-45cf-ad0e-59b1e2120429

Just did a search of the entire machine, hidden and system files included and there is no nmSvc.dll to be found.

I guess this should be in it's own thread.  Can someone make that happen or do I need to start a new one?
Looking at your crash reports, it seems there is a bug on file already which is correlated to the crash signature you are seeing:

 * Bug 714761 - Firefox 12.0a1 Crash Report [@ JSObject::getGeneric(JSContext*, JSObject*, int, JS::Value*) ]

Feel free to comment on that bug report.

Thanks so much and sorry for posting in the wrong place.  Now that I know where to look for crash reports I should have better luck finding the right threads to post in.

Thanks again!
This signature has around ~1300 crashes in the last week across all versions, including some crashes in beta and aurora. The lion's share of crashes affect users that are using FF 12.

I'm coming to this party a little late, but this description doesn't seem to make sense. CE doesn't block *any* websites. It's either logged in or it's not. If you're logged in, you can browse normally. CE just records URLs and may choose to report them to your "buddy" if it finds them suspicious. 

I'm seeing lots of crashes with upgrade to FFX 13.

After feeling like 14/15 were a little better, I get this crash almost every few minutes on my home machine in 17 - I suspect it's related to my slow home connection (~300kbit, maybe less) because I don't see it often at work.

I would be willing to do testing.

Heck I don't know what Mozilla is building with but I would be happy to run under a debugger. Have the CE people offered to provide a version of the DLL with debugging symbols?

I fortunately have not had this crash in a little while. Maybe due to an update for Firefox and/or CE. It also coincided somewhat with my getting a faster connection that it stopped happening. Maybe that has to do with it. This would back up Ari's suspicion. I therefore don't think that I would be of much help at this point.
Ari, this bug was originally filed against Firefox 12, so I would expect the crashes to start happening there. The best way to confirm that would be to try using Firefox 11 and 12 and doing a comparison between the two. If you can crash Firefox 12 but not Firefox 11, it means the bug probably started in Firefox 12 Nightly at some point.

Okey-doke, I'll roll on back and see if things improve.

If I narrow it down to between 11 and 12, is the next step a binary search thru the nightlies?

Guess what folks? 11.0 crashes plenty too.

Continuing on back to 6.0, I guess from there I'll go back to 3.5 or so if necessary. If it still crashes, does everyone agree it's a CE change that caused it?

To that end - would whoever got in touch with the CE people care to share their contact info by private email to me?

Thanks Ari. If it goes back as far as Firefox 4.0 then that pretty much invalidates the assumption that this is a Firefox regression. There's not much point in going back any further than that.

If it's not a regression we will have to consider workarounds (traditionally outreach and then blocklisting in worse-case scenario). However, please focus on seeing if this goes back as far as Firefox 4. Thank you.

One thing that I am still finding with Firefox 17 is that every now and then pages stop loading for no reasonuntil I close Firefox. Once I close it CovenantEyesHelper.exe starts using ~25%cpu+ and nothing can load from the internet until I restart CE. This happens with Opera as well, but not Chrome. Every time I close FF I get high CPU from CE.

Official results are in for the new year: 6.0 crashes too.

Will go back to 4.0 and see what happens.
Thanks Ari, let us know how you make out with Firefox 4.

Scoobidiver, could you please check crash-stats to see where this sits in the topcrash landscape for Firefox 18?

It's #222 top browser crasher in 17.0.1, #254 in 18.0b7 and #985 in 19.0a2.
Given Scoobidiver's analysis, no need to track for upcoming releases. Looks like people have stopped using Firefox/CovenantEyes together.

We've had no success reproducing this internally over the last year. Would you be willing to try to find a regression range for this bug using the nightlies? I can provide guidance as needed.

I had no success getting a regression range. I went back to 6.0 or something ridiculous, it all crashed. Latest also crashes.

In that case this is more likely a bug in Covenant Eyes than it is a bug in Firefox. If we have no hope of success through engaging with Covenant Eyes and can't blocklist the offending DLL from loading, can we at least get a support article posted instructing users how to work around this issue (ie. removing Covenant Eyes or switching to a different browser)?

Additionally, I don't see much point in keeping this bug in the NEW state if it's unreasonable to expect that we'll ever fix this.

For the record, my limited experience indicates that other browsers crash just fine too. Crash may be linked to a race condition - seems to happen on slower machines.
