title: CKEditor + Selenium WebDriver not work with FireFox 9/10 anymore
body: <p>Before moved to FF9/10, this line sendKeys can work well with FF8.0.1 + Selenium 2.18.  But after upgrade FF to 9 and 10, sendKeys will get nothing in CKEditor. No exception, no warning. I am wondering if it is the bug of CKEditor? or FF 9/10?  or WebDriver?  Anyone have clue for this?</p>
  
  <pre><code>DesiredCapabilities desiredCapabilities = DesiredCapabilities.firefox();
  desiredCapabilities.setPlatform(Platform.WINDOWS);
  URL remoteAddress = new URL("http://127.0.0.1:4444/wd/hub");
  RemoteWebDriver driver = new RemoteWebDriver(remoteAddress,desiredCapabilities);
  driver.get("http://ckeditor.com/demo");
  WebElement element = driver.findElement(By.id("cke_contents_editor1")).findElement(By.tagName("iframe"));
  element.sendKeys("Cheese!");
  </code></pre>
  
  <p>Of course, I can access the instance of CKEditor directly like below, but it just a workaround.</p>
  
  <p><code>((JavascriptExecutor) concorddriver).executeScript("CKEDITOR.instances.editor1.insertText( 'hello' );");</code></p>
