About how long before the problem shows?

Start Firefox using Troubleshoot(Safe) Mode {web link}

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

While still in Troubleshoot(Safe) Mode,

Hi Fred,

The problem is sporadic so I am unsure if I can say for sure it happens at X amount of minutes. However, I was able to submit 2 reports while in Troubleshooting Mode.

I will continue to run Troubleshooting Mode while the logs are reviewed.

Thanks!

Basically, an OOM (Out Of Memory) means the system is having issues with the RAM.

MemTest LAST UPDATED : 12/04/2020 Could you please run a tool from http://memtest.org/ in order to check the integrity of your RAM?

You will need a thumb or disk drive to install it on.

Do you let Windows handle the page file or did you set a fixed size ? Control Panel -> System -> Advanced -> Performance -> Settings

If you use a fixed size for the page file then try the former and let Windows handle the page file. How to determine the appropriate page file size for 64-bit versions of Windows {web link}

I intentionally do not run a page file and the previous version of Firefox did not care.

What I did notice is that on the "Firefox hangs or is not responding" document, the first entry there describes about a corrupted Places file. So, I attempted this first. I renamed the places.sqlite file but did NOT find a places.sqlite-journal file to rename. I'm not sure if this could be the issue, but I thought I'd mention it in case this missing file is causing an issue. On relaunch of Firefox the places.sqlite regenerated as expected, but still no places.sqlite-journal file.

Additionally (I probably should have done this one step at a time to confirm which actually resolves the issue), I have disabled hardware acceleration. My graphics card is a RTX 3070 OC with the latest driver (471.11).

I'm not sure how Firefox could run "out of memory" with 32GB, but I will attempt to run the memtest later if this does not resolve with the renamed Places file and the disabled hardware acceleration.

I wanted to stress that this issue did not happen at all on the previous version of Firefox, but started immediately after upgrading to version 90.0. I am aware that this is a brand-new fresh release and issues may crop up, which is part of why I am reporting the issue rather than just shrugging and working around it.
