Crash on Win10+FF+banjo: existing connection was forcibly closed #76

Saw this crash when running the banjo test on Win10 + Firefox:

Not sure what's going on here. I'm assuming it's referring to the connection between selenium<->firefox, but I don't know what would cause the browser to forcibly close that connection.
