Firefox only allows one instance of each profile. If you did not conigure anything for it and your firefox browser is open when starting the test. Firefox blocks selenium from using it.
Firefox 只允许每个配置文件的一个实例。如果您没有为它配置任何东西并且在开始测试时您的 Firefox 浏览器是打开的。Firefox 阻止 selenium 使用它。
Configure a profile in Firefox and you can configure selenium to use a ff profile
在 Firefox 中配置配置文件，您可以配置 selenium 以使用 ff 配置文件
when you run Selenium Server, run with the server with command-line option -firefoxProfileTemplate "path to the profile"
当您运行 Selenium Server 时，使用命令行选项 -firefoxProfileTemplate“配置文件的路径”与服务器一起运行
(in case you didn't configured that)
（如果你没有配置）

I keep having the same issue and have fixed it each time by updating my version of Selenium server to the latest version. It seems that every time Firefox releases a new update it stops old versions of Selenium server from working!
我一直遇到同样的问题，每次都通过将我的 Selenium 服务器版本更新到最新版本来修复它。似乎每次 Firefox 发布新更新时，它都会阻止旧版本的 Selenium 服务器工作！
