I have the same problem I think. I opened a bug report against Firefox
https://bugzilla.mozilla.org/show_bug.cgi?id=1302974

As you can see there it seem that is
"user_pref("layers.acceleration.force-enabled", true);" that make Firefox
crash. If I set it to false Google Maps works. To confirm with a clean profile,
Firefox crash on Google Maps with just this setting enabled
"user_pref("layers.acceleration.force-enabled", true);". Weirdly it make
Firefox crash only on Google Maps. Unfortunately I, and a lot of people I
guess, need this feature to get rid of tearing. Firefox doesn't crash in safe
mode. It don't crash too with HWA disabled.

Here is the section "graphics"
