错误说明了一切：
Build info: version: '2.48.2', revision: '41bccdd', time: '2015-10-09 19:59:12' System info: host: 'xxx', ip: '192.168.43.34', os.name: 'Windows 8.1', os.arch: 'amd64', os.version: '6.3', java.version: '1.8.0_40' Driver info: driver.version: FirefoxDriver
错误跟踪日志明确提到 浏览器客户端 无法识别回 FirefoxDriver 二进制文件。
您的主要问题是所使用的二进制文件之间的 版本兼容性 ，如下所示：
因此， JDK v8u40 和 Selenium Client v2.48.2 之间显然存在不匹配。
