Hi

Thank you for the crash reports, really useful.

Aside from Firefox, what other software have you installed? Possibly something gaming or video related?

Hello Paul, Thank you for your reply.

Here's the list of the software installed (all genuine, nothing is pirated) and there are no malware on my device by the way.

Internet Download Manager HMA VPN K-Lite Codec Logitech G HUB Office 365 iTunes AdGuard AltServer (iPhone Jailbreak related) Discord Nvidia gaming software + Drivers Winrar Telegram Firefox addons: Ublock Origin + IDM + Return YT dislike button

and the rest of Windows 10 already installed apps like Skype, paint and others (it was a clean install no bloatware)

The only game I have installed is World of Warcraft.

Edit: forgot to mention that sometimes Firefox freeze and the taskbar freeze as well. Only solution would be to restart Windows Explorer form the task manager.

Do you have the same issue with Firefox in Safe Mode? https://support.mozilla.org/en-US/kb/diagnose-firefox-issues-using-troubleshoot-mode#w_how-to-start-firefox-in-4troubleshoot-modesf5safe-modesf

Are you running pro or home version of Windows? If pro, you should have sandbox enabled for testing. https://www.howtogeek.com/399290/how-to-use-windows-10s-new-sandbox-to-safely-test-apps/

What security software are you running?

Okay, thank you.

When looking through the crash reports,I saw mention of a problem with msmpeg2vdec.dll. A little research online revealed that people having problems with this relating to software from Blizzard.

As a first step, I would make sure that you have all Windows updates, in particular anything relating to video.

Hello jonzn4SUSE,

I do not use any anti-virus since like 10+ years. I am a cautious user and never had any issues.

Thanks for sharing the links. I will try safe-mode later.

Hello Paul,

I have the latest updates for everything. Including Windows, Office, NVIDIA, etc.. all is up to date.

I will look into msmpeg2vdec.dll online. Thanks again.

I forgot to mention one very important information:

When Firefox used to crash I suspected somehow that it is something to do with the graphics card.

So, I made Firefox function only on the GPU of Nvidia and not the GPU of intel CPU.

That reduced the crashes, but they still occur.

Anyone has any idea of this might occur?

What make and model computer? What model graphic cards are installed? I like the update tool from intel. https://www.intel.com/content/www/us/en/support/detect.html Install the app and let it verify drivers are current. Here's the page for Nvidia. https://www.nvidia.com/Download/index.aspx?lang=en-us

Hello jonzn4SUSE,

Thanks for the information. It's a custom build, every part is from a different brand.

Here's the update on the issue:

About two days ago I came across a comment on the internet of someone saying to disable: Use recommended performance settings Use hardware acceleration when available

And I did. The crashing went away (for now)

So I guess Firefox and my hardware are incompatible.

Anyway, thank you everyone for helping me. I appreciate it.

Boot the computer in Windows Safe mode with network support to see if that has effect in case security software is causing problems.
