The crash reports are OOM (out of memory) reports where not enough contiguous free memory is available.

  • MOZ_CRASH Reason (Sanitized) : [unhandlable oom] Failed not allocate new chunk during GC
Available Page File : 597,700,608 bytes (597.7 MB)
Available Physical Memory : 6,699,831,296 bytes (6.7 GB)
System Memory Use Percentage : 60
OOM Allocation Size : 1,048,576 bytes (1.05 MB)

Do you let Windows handle the Page file automatically or have you set a fixed size for the Windows Page File ?

  • Control Panel -> System -> Advanced -> Performance -> Settings

If you use a fixed size for the page file then try the automatic setting and let Windows handle the page file automatically.

Changed the page file size to be managed automatically. That's all well and good, but I wonder why the problem recently started happening.

Maybe you are running other software that uses a lot of memory. You can possibly check this in the Windows Task Manager (Ctrl+Shift+ESC).
