Certainly. If you would like more just ask.

Thank you again

ok, it looks like that's an issue with hardware acceleration - please try to disable hardware acceleration in the firefox menu > options > advanced > general for a while and see if the crashes continue.

Hardware acceleration is not currently enabled, it was one of the earlier settings I changed in an attempt to fix this.

The box "use hardware acceleration when available" is NOT checked.

can you test if it's possible to uninstall the microsoft platform update numbered kb2670838 from the list of installed updates from your system?

http://windows.microsoft.com/en-us/windows/remove-update

There are other things that need your attention.

Your System Details List shows multiple Flash plugins.

1. Shockwave Flash 13.0 r0
2. Shockwave Flash 12.0 r0

You can find the installation path of all plugins on the about:plugins page.

• http://kb.mozillazine.org/Issues_related_to_plugins#Identifying_installed_plugins

You can check the Flash player installation folder for multiple Flash player plugins and remove older version(s) of the plugin (NPSWF32) and possibly (re)install the latest Flash player.

• (32 bit Windows) C:\Windows\System32\Macromed\Flash\
• (64 bit Windows) C:\Windows\SysWOW64\Macromed\Flash\

Both of these have been completed. I will update if another crash occurs after tomorrow night, which is roughly when it is expected with the current frequency.

Thank you for your assistance.

I also got this issue, however it sometimes only takes 15 minutes of idling for firefox to crash. Usually I got 2-3 firefox windows open with total of aroud 50-100 tabs. Here are two most recent crash reports:

Hi Spirit

Those two crash reports show a rather high System Memory Use Percentage of over 80%, so there might be out-of-memory issues.

They might also be hardware acceleration related, so you can try to disable hardware acceleration in Firefox (you need to close and restart Firefox).

Crashes are continuing, the other 3 crashes are: bp-1a0f346c-7ec6-40a6-adab-c68862140505 5/4/2014 11:01 PM bp-aafe5101-e077-4c65-984b-2cc8c2140504 5/4/2014 10:14 AM bp-202f953f-228a-4752-a14d-36d262140504 5/4/2014 12:33 AM

Hi echofilter

Did you try to disable hardware acceleration?

Hi cor-el,

Thank for you quick response. Hardware acceleration is and has always been disabled on my firefox install. I did double check and it is disabled. Well my system got GB of ram so even at it's highest crash (87%) it still has over 1gb of free ram. I was running virtual machine at during both of those crashes, so the memory usage was quite high. However while I was sleeping it has crashed again:

bp-b2834969-cf4a-481b-8fee-9e96b2140505 5.5.2014 13:24

This time the memory usage was at 75% so there was 2bg of free ram. I've been running this system for few years with constantly over 60% memory usage and it has never before been an issue. The system is stable even with my usage. I've used Prime95, IntelBurnTest, Memtest86+ etc. the system has passed them all. Current uptime is over 23 days. It isin't longer because I need to restart to install updates. Firefox crashes began right after the update to v29. Memory usage is high on win7 x64 because of the way the memory management works - the more memory you got more will be used. Once you go over 90% system starts to free cached memory from programs aren't running.

Create a new profile as a test to check if your current profile is causing the problem.

See "Creating a profile":

• https://support.mozilla.org/kb/profile-manager-create-and-remove-firefox-profiles
• http://kb.mozillazine.org/Standard_diagnostic_-_Firefox#Profile_issues

If the new profile works then you can transfer files from a previously used profile to the new profile, but be cautious not to copy corrupted files to avoid carrying over the problem

• http://kb.mozillazine.org/Transferring_data_to_a_new_profile_-_Firefox

Just an update: With the profile post I decided to go all the way and back up my profile and extensions but completely uninstall firefox and reinstall it.

It had realistically probably been too long since I had done a clean install. As of now I haven't had a crash in over 12 hours which is already longer than previous times. If by tomorrow I have not had a crash I will mark this as solved with the new profile post.

Thank you again for the assistance

After creating new profile I haven't had an idle crash. However I had an crash during use. Maybe it was just a glitch.

I spoke too soon. Had an idle crash during last night.

bp-1613ead8-781c-42e7-9968-d839d2140507 7.5.2014 12:04

Yet another idle crash. I was idling for less than 45 minutes.

bp-be8a0322-67e7-4045-b4b5-d01922140507 7.5.2014 16:19

After reinstalling firefox and creating a new profile (and restoring my extensions, and bookmarks, but nothing else) I have not had a crash at this point in time.

I will reopen a ticket if it begins again. My tab usage is not back to 50+ yet, as I forgot to save my history. At this point if it begins after being over 50 tabs it will be apparent just what the cause is anyway.

FWIW I have 16 gig RAM consistently under 40% usage unless multitasking with a game in the background.

Thank you again for the assistance, hopefully it will not reoccur once my tab usage becomes high again.

Hi Spirit_

These are still likely out-of-memory type crashes as also is pointed out in a bug report this is attached to the crash report.

• https://crash-stats.mozilla.com/report/index/be8a0322-67e7-4045-b4b5-d01922140507

• bug 805406 - crash in gfxContext::PushClipsToDT with Direct2D 1.1 (d3d11.dll 6.2 or 6.3)

Please do not comment in bug reports
https://bugzilla.mozilla.org/page.cgi?id=etiquette.html

Hate to reopen what I thought a reinstall had fixed, but it does seem the crashes have returned.

Pertinent logs are currently bp-0097400c-d5f9-44bf-a9b0-0a0cc2140530 5/29/2014 9:23 PM 7ba3df8a-ab57-45f4-9c6c-a70d490600fa 5/29/2014 11:52 AM bp-184cd970-2e03-44a8-9810-0ad1a2140529 5/28/2014 5:12 PM

The only difference I can specifically mention is occasionally from background tabs the browser window will go black and i can see the "background tab" in my current tab focus. If I do not close firefox manually it will eventually crash. I would not be surprised if this is related to me coming back to a FF crash. By all means if I can provide further information please ask.
