Selenium启动Firefox报错Failed to connect to localhost/0:0:0:0:0:0:0:1:4560

一、问题描述

java代码没问题，但是控制台，却出现如下错误：

你的端口号可能不是4570

二、问题解决

你绝对找不到解决办法，因为我找过了，除了Google不能访问，其他的网页我都看，就一个Stack Overflow 上面的，解答还靠点谱，如下

但是我按他的办法，反正是没解决。但我由上面的解决方案猜测，一定是selenium、webdriver和Firefox之间版本的问题应该跟jdk的版本没关系。我觉得主要是webdriver的原因
解决办法

1、selenium3.141.59、firefox71版本不变，降低webdriver的版本

（我火狐webdriver的版本是最新的0.26，要求匹配的Firefox版本必须>=60）
perfect！，试了0.25和0.25都行
