Firefox crashes Windows OS

I have been experiencing lately quite few Firefox crashes that bring down the entire (desktop) Windows OS in a brutal manner: complete system lockup, instant reboots (no blue screen).

These seem related to the audio and video interactions with the host system - streaming musinc online ( or engaging in graphic intensive activities. This supposition propmpt me to perform few hardware tests - memory, GPU, audio card,etc. Everything checks out fine with the basic test and diagnostic tools I've used.

The worse system crashes have happened while on the wesbite trying to purchase passes. Along the way for signing the waiver, the site brings up a graphical pad for capturing the guest's signature using the mouse. Several attempts have ended with horrendous system crashes (I had to locate the hardware reset button on my system, which took a while), never in the same spot in the process. Similar issues have happened on my wife's laptop (Windows 10 OS) while using Firefox on this site. I had to use a different browser to complete this purchase, for both my kids sanity and my system health. (for whomever is interested in troubleshooting this site, just follow the prompts and add guests - the purchase step is the very last one).

I should mention that Firefox' own crash page (about:crashes) shows no sign of any crashes. Other times, the Firefox window just dissappears without any warning, and no traces of crash information in Firefox nor OS event system. My system is configured to save a memory minidump in the event of crashes - there were none.

In this context, I could be wrong, but narrowed the culprit down to Firefox itself. In my opinion, whatever Firefox is doing to bypass OS basic protection mechanisms (and let's be honest - on Windows these can be better) and cause such hard failures are a dangerous vulnerability that should be investigated.

Any ideas and suggestions on diagnosing this or what to capture for aiding with troubleshooting, are appreciated.

Thank you FredMcD for suggestions. To report back on those:

  • the graphic driver was already up-to-date (NVIDIA)
  • I did create a brand new profile and tried to go through the website that gave me troubles before. It worked fine all the way through.

The new profile did not activate any of the extensions I have in my regular profile - the password manager, Antivirus - nor logged in to Firefox account. Not sure what to make of it - on one end a new profile seems to improve things, on the other there is a bit of a hassle to reconfigure it and rebuild the authentication and identification for quite few websites I'm using. I'll have to think about that... Nonetheless, irrespective how corrupt/misaligned a browser profile becomes, it should not lead to crashing the whole system.

Start Firefox in Safe Mode {web link}

A small dialog should appear. Click Start In Safe Mode (not Refresh). Is the problem still there?
