Question

我正在使用selenium-server-standalone-2.28.0.jar。推出了枢纽和使用以下命令

启动侦听器

"C:\Program Files (x86)\Java\jre7\bin\Java.exe" -jar selenium-server-standalone-2.28.0.jar -role webdriver -hub http://localhost:4444/grid/register -port 5557 -browser "browserName=firefox",maxInstances=5,platform=WINDOWS,javaScriptEnabled=true,TAKES_SCREENSHOT=true

打开一个空白的Firefox窗口，然后显示以下错误：

Execute

在调试时，转到Firefox浏览器附加组件列表，发现Firefox webDriver与Firefox 20.0不兼容目前的Firefox webdirver版本为2.28.0

我可以使用哪种最新的Firefox版本，还是有任何替代方案可以解决这个问题？

Answer 1

使用最新版本。现在2.32.0

见http://docs.seleniumhq.org/download/ 或直接下载http://selenium.googlecode.com/files/selenium-server-standalone-2.32.0.jar

它对我有用

Answer 2

Firefox 20刚刚问世，Selenium开发人员可能需要花费几天的时间来修复已经出现的任何兼容性问题。

最新版本的Selenium是2.31.0（可用here），它可以与Firefox 19.0.2一起使用。任何版本的2.30.0以下的Selenium都无法与FireFox 19及更高版本一起使用，因此我建议您先尝试将Selenium更新到最新版本。

要清楚我尚未下载并尝试使用FireFox 20，因此我不知道Selenium 2.31.0与它的兼容性。

Answer 3

我有Ubuntu 12.04 64bit。最近更新到20后，Selenium停止工作。我正在使用Eclipse（JDK 7）。我将Eclipse.ini更改为使用JDK 6，它开始工作。 Webdriver偶尔挂起，但大部分时间都在工作（这可能是我正在测试的网站的问题）。为了安全起见，我现在禁用了Firefox自动更新。

Selenium WebDriver无法与Firefox 20连接
