Click does not work in WebDriver 2.39 + Firefox 26

[lukeis]

Originally reported on Google Code with ID 6774

WebDriver 2.39.0 does not click on elements in FF 26 with native events enabled. The
following example DOES work in 2.38.0 with FF 26 and in 2.39.0 with FF ESR 17:

DesiredCapabilities caps = DesiredCapabilities.firefox();
//caps.setCapability("nativeEvents", false);
WebDriver driver = new FirefoxDriver(caps);
driver.manage().window().maximize();
driver.get("http://google.com");
driver.findElement(By.id("lst-ib")).sendKeys("webdriver");
driver.findElement(By.name("btnK")).click();

btnK element is never clicked, no error is reported either. If commented out line is
uncommented, everything works. The problem was reproduced both with Java and Ruby bindings.

Now to the tricky part. The same code does work on some machines. It seems that some
people have reported problems with 2.39.0/26.0 combination already, so this is probably
not a local issue. I have also attached the log produced by Firefox extension, maybe
it helps.

Would appreciate any ideas on where else to look for the cause of this issue.

Selenium version: 2.39.0
OS: Windows 7
Browser: Firefox
Browser version: 26.0 (en-US)

Please open the system display settings and ensure that font size is set to 100%, see
the attached screenshot.

• Merged into: Firefox 23+ Click() does not work if display settings is different from 100% #6112

But why is this issue not fixed. Isnt it supposed to be working with display settings
anything other than 100%??
