User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:43.0) Gecko/20100101 Firefox/43.0
Build ID: 20151210084639

Steps to reproduce:

I installed Firefox from the Google Play Store on my new Yoga 3 Pro x86 tablet. Firefox's "about:" screens and simple sites work fine, but if I load a larger web page and load more, scroll, or zoom, then Firefox often exits. E.g., it dies on a pinch-to-zoom gesture on Slashdot.org.

Actual results:

Firefox dies, returning me to Android's home or lock screen. I never see a Firefox or Android crash reporter and there's nothing in about:crashes.

I reported this in https://support.mozilla.org/en-US/questions/1098598#answer-820785
I installed nightly fennec-46.0a1.multi.android-i386.apk and get the same behavior.
I got adb<->Web IDE working and I don't see any useful output in that.
I used `adb log` to get the Android log (attached), and it has 
  I/ActivityManager( 4378): Process org.mozilla.firefox (pid 21884) has died
the last output from process 21884 is
  V/GeckoDynamicToolbarAnimator(21884): Changing animation to immediate jump
  V/GeckoBrowserApp(21884): On pan/zoom stopped, short page: false; atBottomOfLongPage: false

Expected results:

No silent exits :-)  I'm a long-term user of Firefox for Android on my 2013 Moto X without this issue.

Someone else reported Firefox (and Chrome) crashing on the same device in the Lenovo support forums, https://forums.lenovo.com/t5/Android-Yoga-Series-Tablets/Poor-browser-performance-and-crashing-on-Yoga-Tab-3-pro/m-p/2235355

Is there anything I can do to help debug this, like run a debug build? Any web guide to using `adb` or other tools to at least identify what Firefox is doing when it exits?  Can I bring the tablet to the Mozilla S.F. office with cookies, coffee, beer?  Without Firefox I've just bought an expensive black mirror.
