Probably a dup of bug 1304971.

Reproduced this issue, actually Firefox crashes when starting the new presentation from the second device https://pastebin.mozilla.org/8924104

Reproduced this on Nexus 4(Android 5.1.1) and Nexus 6(Android 6.0.1), the reproduce rate is about 1 out of 2 tries.

based on the information in comment #3, this should a duplicate bug to bug 1313404.

I wasn't able to reproduce this issue anymore on this build https://people-mozilla.org/~schien/presentation-api/fennec-52.0a1.en-US.android-arm.apk

The build you pointed here is a release build so this crash should never happen.
