On Mac Systems, Firefox and Selenium are incompatible

Workaround, check the environment:
Python 2.7.10
Firefox version 46
Selenium 2.53.6

Note: The Firefox automatic update is turned off, otherwise the selenium use case may not be executed after an automatic upgrade.

The error is as follows:

This question is the same type of problem as the one previously summarized:
