I had to stop firefox and start it again. Now it seems to be stable. Any idea what was causing this?

Are you running a wayland environment with hardware acceleration enabled?

No. This is gnome+X11

It happened again. I now have 9075 firefox coredumps just for today

I get no coredumps with firefox 98 (using Xfce).
Is it possible that some required update is missing?

This time I started firefox from the console and I am getting and endless list of this:

A simple google search for “ryzen 7 3700x Linux ryzen 9 5900x” triggers the coredumps
And I have to say that this was never an issue before and firefox-esr does not give me that message or any coredumps.

Have you tried disabling hardware acceleration in firefox?

I guess I found the solution.

The issue comes when media.ffmpeg.vaapi.enabled = true as it is in my case. I can either set it to false to fix the issue or, even better, keep it as true and set MOZ_DISABLE_RDD_SANDBOX=1 before starting firefox.

This is a very serious security risk and even more so if you are using a “web browser”. From https://wiki.archlinux.org/title/firefox#Hardware_video_acceleration

As a last resort, the content process sandbox can be disabled. However, this is a serious security risk and disables protection against attackers. It is recommended to leave the sandbox settings as default [18].


Here’s what you can do now:

  • Disable HW on firefox tiil the issue is fixed (Don’t downgrade!)
  • Switch to Chromium.

Did you try firefox-developer-edition if it has this fixed?

yes this issue seems to be not happen on firefox nightly (99)

Thanks for mentioning the security aspect. I will do as you recommend.
