Selenium opens browser but doesn't load page

I did not add geckodriver to PATH (it is located in the same directory as Python script), and after the Selenium update to 3.0.1, use this code to start a Selenium session:

gecko = os.path.normpath(os.path.join(os.path.dirname(__file__), 'geckodriver'))
binary = FirefoxBinary(r'C:\Program Files (x86)\Mozilla Firefox\firefox.exe')
driver = webdriver.Firefox(firefox_binary=binary, executable_path=gecko+'.exe')

Additionally: you need update geckodriver to the latest version, 0.11.1.
