Crash Data

User Agent: Mozilla/5.0 (Windows NT 10.0; WOW64; rv:55.0) Gecko/20100101 Firefox/55.0
Build ID: 20170803103124

Steps to reproduce:

I upgraded to Firefox 55.0 (32-bit) this morning.  Prior to the update, I was running as described below with no problems.  In addition to below, I have modified my start page (starting when Firefox first moved to this style several releases ago).  New tab address is same as before, but I modified the parameters to use my own new tab instead of default layout.  I use New Tab Homepage Add-on/Extension to manage this.

I run Firefox every day.  I use multiple tabs each time - usually 10 or 12.  I was browsing Wikipedia on one tab when it crashed the first time.  I was browsing SI.com on one tab when it crashed the second time.  Wikipedia home was still up on another tab before crash.  All other tabs were on my home/start page.


Actual results:

First time (crash): received notification of crash.  Asked to send info to Mozilla.  I declined and continued; browser crashed.
Second time: I was prompted that there was a problem and Firefox would crash.  Did I want to debug.  I initially answered yes, but it selected Visual Studio 2010 as the debug tool.  I then answered to cancel debug.

I was running the most current previous release before updating.
Result of initial browsing: entire browser crashed; all tabs, of course, went down.  I have seen crashes before on newly released versions, so was waiting to see if an update was forthcoming.  Since nothing showed up, I logged this bug.  Firefox has crashed on each time using with my "normal" number of tabs open.  Only 5 tabs open now.  I will test to see if it only happens once tabs use all space across window banner or regardless of number beyond "1."


Expected results:

Simply stay up and running with all tabs as it has for many releases.
Please send a crash report and paste the ID here. Otherwise there's no way to fix it. Details: https://support.mozilla.org/kb/mozillacrashreporter

Will do.

Also, running Windows 10 64-bit.  Forgot to put that in before.

Looks like your graphics driver is causing the crash. Try updating the driver: https://support.mozilla.org/kb/upgrade-graphics-drivers-use-hardware-acceleration
Component: Untriaged → Graphics
Product: Firefox → Core
Can you update your graphics card driver and try again?
Flags: needinfo?(ericg09)
I really do not agree with the assessment fully.  All things being equal, if all is working on a system fine for weeks or even months, if one item is introduced and it immediately begins failing itself, then it must be the problem.  I have been in s/w and systems for over 20 years...Windows, UNIX, Linux, etc.

That said, if the new version of Firefox, 55.0, has introduced some new feature that exposes a particular issue with the graphics adapter, especially a common one, it would make sense that the issue would be found and communicated.  I have been running Firefox versions from before the new tab configuration in modern releases until the current 55.0.  This is the first release in years with which I have had issues.  It has crashed twice already this morning (10:59 and 11:06 local time; now 11:25 local time).  Once I was viewing something with possibly active content / videos on www.si.com; had a few tabs open, but not normal 10-12.

Since graphics were suggested, however, I did do a scan for updated drivers, and I also had both a push of updates (Windows) controlled by our IT department, and a prompted update of BIOS and system drivers for the Lenovo laptop (P50) itself.  The windows push from IT happened a day after first reported crashes.  The BIOS update was this morning prior to the most recent crashes.  Between, but after the suggestion that there was a problem w/graphics, I manually ran driver update on the Intel graphics from Device Manager.  It did download and update.  I also ran on the NVidia but it did not find a better driver.

I have been running the same monitor configuration since getting the system in May, 2016:
2 x Lenovo 23"  attached via docking station by DisplayPort cables
1 x Dell P2210 attached via docking station by VGA cable

I am assuming the crash report has this data, but here is quick graphics summary:
Current Drivers:
Intel HD Graphics 530
Driver date: 11/11/2016
Driver version: 21.20.16.4550

Events indicate activity for installation request 7/28/2017 and 8/9/2017

NVIDIA Quadro M1000M
Driver Date: 5/1/2017
Driver version 22.21.13.8205

Events indicate activity for installation request only 7/28/2017

I believe the 7/28/2017 is the item mentioned about (IT Windows update push).  8/9/2017 was my manual update.

I am currently checking the NVidia, Intel, Lenovo, and Dell sites for latest for both graphics adapters and potential monitor drivers.
Flags: needinfo?(ericg09)
I completed all updates; all graphics items were updated to latest manufacturer's versions where fully supported.  Dell P2210 monitor is not directly supported on Windows 10, but it is using generic driver, so it should be no problem.  Also, it has been part of the configuration from the beginning.  (BTW - even though it does not really matter, the Dell P2210 was not where the Firefox sessions were running during any crash.)

After mfr. updates, ran the full Lenovo System Update scan, downloading and installing ALL updates.  14 Lenovo updates installed, including another chipset update.

Prior to these two steps above (today), on 7/29 and 8/9 (2017), Windows updates were pushed in two large batches, resulting in 185 updates being installed across those two days.

All this was done, reboots, etc., and FF 55 crashed again with multiple tabs open, viewing a short video on si.com.

If this is not resolved, I will either uninstall FF or revert to 54 if possible.

Also, I don't understand why sometimes when FF crashes it asks for debug vs. presenting options to "Tell Mozilla" about crash.  The "debug" ones do not get reported in the Crash Reports area as either reported or unreported.
Key to note: I have had no crashes of either IE 11: Version 11.540.15063.0 or Chrome Version 60.0.3112.90 (Official Build) (64-bit) during this entire time, running similar or even same items since FF will not stay up.  For many years I have almost exclusively used FF from work and home for most internet access rather than IE (or Chrome) due to overall stability, security, flexibility of configuration.  Would like to continue...

In addition, I have had no crashes or strange performance of any other applications noted as yet since upgrading to FF 55.0.  If other items do crash, will report.

Last crash, I was specifically running a video on si.com (testing FF) and clicked on the timeline in the video to advance it to that point when it crashed.  This time, again, it prompted me to debug or close application.  I closed.  Not going to run debug, but would prefer it to run the crash reports.

Would love to continue to assist with info gathering and troubleshooting, but it is eating into workday and I simply needed to get a browser that would work for these purposes.

I uninstalled Firefox 55.0, downloaded back-rev 54.0.1 (64-bit).  Ran it all afternoon 8/11 with no issues; viewing same videos on www.si.com, plus running music off youtube, having gmail open, and using other tabs for tech searches on other sites, etc.  Had 12 tabs open concurrently +/- when opening docs opened a new tab.  54.0.1 works great!  I will try 55.0 only when I see a different version number indicating a fix.  I would also love to know if there is a way to install multiple versions rather than in-place replacement/upgrade?  If so, I would grab more crash info.  Perhaps it is an option I did not see on install...
Hello ericg09,

Could you post the information in about:support page from firefox 55 for me? There are some further information to help me to investigate the crash.

Are there specific steps to reproduce the crash? or it just crashed while normal usage?
From comment 0 and comment 7, it seems related to video playback, did these crashes happened when there were videos playing?
Flags: needinfo?(kechen) → needinfo?(ericg09)
I would like to confirm similar behavior as Eric. Since I installed FF 55, both 32 and 64 bit version have seen multiple crashes. I have not had one session where FF has not crashed on me. 64 bit version never gave me a bug submission option, so i downloaded the 32 bit version. On the restore crashed tab page, I selected the option to submit the crash report.

I have a Nvidia Quadro 2000 Graphics card and all drivers were updated from Dell, and then from Nvidias website.

I have uninstalled Flash plugin, initially thinking that to be the cause, but no help.

Some of the crash reports ID:

Please let me know how can I help in troubleshooting.

regards
Some more Info:

Nvidia Quadra 2000 driver version: 21.21.13.7755

Most of the times, I see it happens on websites which have video elements in them. Facebook, cnet etc. But I don't need to run the video to crash it.
Bug is apparently still not fixed in 55.0.3 (64-bit).  I updated to this today.  I repeatedly get errors when I browse www.si.com.  The specific steps used to reproduce the issue today:

1. Open site.
2. Click on and hold "MLB" link in the banner area near top of page.
3. Select "Standings" from the list.
4. Click on the "Roster" link once page has displayed.
5. Scroll down and select a player from the list.

"Firefox has stopped working."

above error will display w/cancel button.  Cancel works, but Firefox crashes.  If allowed to continue, it will go to "Debug" or "Cancel" w/same result eventually.  I do not waste the time to go down the debug route now.

Conveniently, it appears to not be generating crash reports (since 8/10/2017):

I will be reverting back to 54.0.1 (AGAIN!) if this error happens one more time (4 x in less than 30 minutes).
Reverted back to 54.0.1 (AGAIN!).  The last time, I went to www.youtube.com and simply clicked on a music video.  Crash!  Reverting back to 54.0.1 before provided a very reliable and stable browsing experience.  Same for today.  If memory serves me, I have had no crashes on Firefox 54.0.1 since initiating this bug report.

If 55.0.4 comes out or is advertised to my update tool, I will try it.

This has also been reported at https://support.mozilla.org/en-US/questions/1173566
Crash Signature: [@ nvwgf2um.dll | BaseThreadInitThunk ]
Any reason why this wont be fixed? Or I am incorrect in my understanding and this will be fixed later. Please do let us know, so that I can decide to when to stop using FF, as right now in its current state it's unusable.

Thanks.
Specific to a release that's already had the last build before release (56) and one that's about to stop being a release (55), so, yes, we didn't won't fix this forever :)
Thank you :) I am still getting used to reporting and understanding the bug reports here. I hope it gets fixed by 57. It will be such a buzzkill if I wont be able to use 57. Super excited for it!
maroonmoon, if you can reproduce this at will, and since it started with 55, any chance you could run mozregression tool [1]?  That would help us pinpoint the culprit that regressed this and aid us a great deal in fixing it.  Right now, the information in the crash reports tracked in this bug are so sparse, it's really difficult to move it forward.

Flags: needinfo?(muk.anc)
sure, I will give it a go.
Flags: needinfo?(muk.anc)
By the way, we're also having a side conversation with Nvidia about this, as it seems to be specific to configurations with Nvidia graphics cards.
Hi,
I did run Moz-regression between version 54 and 55. and this is what I got:

If this is showing up in 55 but not later versions and presents as random heap corruption, it's likely bug 1362764, which was fixed (via bug 1386957) in 57 and uplifted to 56 but not 55.
Flags: needinfo?(padenot)
Just to be clear, this happened to me on both 32 and 64 bit builds. THe audio bug seems to be 64 bit specific.

The underlying bug affects both architectures, but will present in different ways due to heap layout differences.
I can wait till 56 releases and keep monitoring. In case the bug still exists, I will update the ticket. The good this is I can consistently replicate it. I just need to run a video on youtube. Also, I noticed that the browser will not crash on youtube ad video, only when the actual video started playing, would it crash.
I'm assuming this is a problem with the latest nightly as well?  Can we have one of the crash reports from nightly?
Flags: needinfo?(muk.anc)
I havent tested any nightlies except those with Mozregressin, which were all before version 55. I can quickly test the latest nightly. Will that be version 57a or something?
Flags: needinfo?(muk.anc)
Yes, it would be a 57.  Thanks!
So, in some limited testing with latest nightly, I don't see it crashing on youtube. I will run it a few more days to confirm.
I think we can close this bug now. I haven't had any more crashes in 57 nightly. Appreciate the help :)
So, since I originally logged this specific Bug 1388437, I would like to understand (for the general public) if we have to wait until Firefox 57 comes out in the mainstream, if the fix will be back-ported to 55.x releases, or if there is a simple alternative method for getting "57" directly?  I am not a developer, just a tech heavy user.  However, if getting the developer edition is the answer, then I can do that.
ericg - because there may be different manifestations of the same problem, or perhaps even different problems, picking up the dev edition is the quickest you can get to the version 57 that has the fix.

However, if you try 57 and you still see this problem, please reopen this bug.

Still having crashes on Firefox 57 (57.0b5 (64-bit)) along with Firefox ESR 52 (52.4.0 (32-bit)).
e.g.
https://crash-stats.mozilla.com/report/index/3c73b729-11f3-48b2-a397-961f90171005
Last observed on 55.0.3 (64-bit) was single tab crashing rather than the entire browser when performing same/similar work on same/similar pages with videos, etc.

Installed 56.0 (64-bit) today to determine if I will see same behavior.

Have been running nightly, multiple versions (upgrading most of the time when prompted), with no crashes for 2+ weeks.
I have been running Nightlies, and released 56 without a single crash. May be what George got is something else. I had the same behavior as Eric of single Tabs crashing in 55, but that's how it should be with separate tab processes.
