现象： 访问 百度加载都很慢，加载图片有时也很慢甚至加载不出来，看视频的开始加载也慢。 最近Edge浏览器更新（版本 86.0.622.69 (官方内部版本) (64 位) ）遇到这个问题很是烦恼，试过很多办法，清 缓存 、清DNS、关闭代理、重置、甚至重装浏览器，均 没 有得到解决，后来确定是新版本的设置问题。 结论：Chromium内核的浏览器在新版本（ Chrome 83开始\Edge 86.0.612.0开始 ）中添加了“安全DNS”功能，而安全DNS功能默认提供的是国外的服务商，所以国内使用该功能会出现网络加载

最近发现我的 Chrome 和新版edge 访问 网页特别慢，每每要等好久，甚至还不如普通的edge了，然后就去网上找了两种可能有效的方法，第一个是我自己试过的，感觉有用，第二个是知乎点赞比较高的，作为记录，下次要用就来看看 # 创建 Chrome 浏览器实例 chrome _options = webdriver.
