I have been using Selenium 3.0.0 beta2 with the Firefox 48.0.2 and geckodriverv10.0 for win 64.
The problem is that the browser crashes without closing.
> [Child 10232] ###!!! ABORT: Aborting on channel error.: file c:/builds/moz2_slave/m-rel-w32-00000000000000000000/build/src/ipc/glue/MessageChannel.cpp,

And it passes the test case.
I tried with FF 46.0.9 as well still gives the same error.
