Hello, on Debian 12 I have seen the same lockup symptoms that you describe that seem to be related to Firefox 128.13.0esr, and I have found it seems to not occur if I disable the "Use hardware acceleration when available" setting in Firefox. In my case, I suspect that this might be because my older graphics card (AMD "OLAND") is slightly unsupported by the available driver, at least that is how I understand this message in the kernel log: kfd kfd: amdgpu: OLAND not supported in kfd In some situations I see possible indications of this, for example when mousing over the timeline on a youtube video, Firefox renders the video thumbnail preview as just a pattern of lines, which is suggestive of a direct memory access problem. Which of course is not a good thing. When the lockup occurs, I guess that is because the graphics hardware is scrambled and needs reset. It is possible to ssh into the machine when it is locked up, and everything except X-Window graphics seems to be running ok. And the only way I have found to reset the graphics hardware is a hardware reboot. But I'm pretty clueless about display graphics, if anyone knows a better way or has other advice. But currently all the essential things I need do work, so I will contine with this situation until that is no longer true.
