Firefox Webdriver is disabled when running a test in selenium webdriver

Question

I had a problem where running a test using selenium webdriver in firefox starts the Firefox browser with the firefox web browser disabled, as shown below.

Because of this, the test run time with an error

org.openqa.selenium.WebDriverException: Failed to connect to binary
FirefoxBinary(C:\Program Files\Mozilla Firefox\firefox.exe) on port 7055; process output follows: 

If I quickly turn on the webdriver and restart the browser, the test will be able to start and finish by itself, so I assume that the problem is that this add-on starts when the test starts. How can i fix this? Thank!

Try to completely remove the extension. Usually Seleniums FirefoxDriver is enough to run the test.

WebDriver driver = new FirefoxDriver();

This should work without any external Firefox plugins.
