For the past couple of days, I have been getting this crash often upon launch8ing the browser.

I have only had this occur on my Samsung Galaxy tab 2 7.0.  I do not get this issue on my nexus 7 2012.

From the crash-stats there's also a lot of crashes with the signature java.lang.UnsupportedOperationException: JNI Function called before it was loaded at org.mozilla.gecko.gfx.NativePanZoomController.handleTouchEvent(Native Method) 

Both of these are happening because native functions are getting called in NativePanZoomController before libxul is loaded, and the function implementations are actually available. We should avoid doing those calls. I'll cook up some patches for this.

These don't need to be native right now. Maybe not ever.
