当我使用Selenium进行自动化测试时，我遇到了一个问题，以下是所有场景：
页面顶部有几个选项卡，现在我想点击这些选项卡并填写这些选项卡下的所有表单，但如果我在formA下提交tabA，那么我无法自动导航到其他选项卡。如果我没有提交表格数据，那么问题就不会发生。这是日志：

此错误消息...

...表示初始化WebDriver / Web浏览会话时出现网络错误。
但是，主要问题是，对于有效和绝对URL的这些网络错误，WebDriver实例应该是预期的，即根据更新的null，驱动程序返回值为Go Command Spec的Success值。 WebDriver应返回Error，错误代码未知错误。
这个问题仍在等待Selenium团队通过Issue#4475，GeckoDriver团队将通过Issue#770解决这个问题，这取决于Mozilla问题ID#1312679
