Some questions:

1. Can we get an about:memory report?
2. Does this reproduce on 1.3?

From the log, it should be LMK problem. It seems loading map will consume a lot of memory (the geolocation information from google map is too big) and trigger LMK.

I have worked with the reporter but was unable to reproduce this issue on both today's build and the build it was discovered on.

Device: Tarako 1.3T MOZ

The help screen loaded slowly but without an error.

This also did not reproduce on 1.3 Buri.

The help screen loaded quickly after opening the page without errors.
