Running webdriver with proxy InvalidArgumentError

Question

i am trying to run webdriver.Firefox() using proxy i seached for multiple solutions and each time i check my ip there is no change , one solution worked for me which is :

def install_proxy(PROXY_HOST,PROXY_PORT):
    fp = webdriver.FirefoxProfile()
    print(PROXY_PORT)
    print(PROXY_HOST)
    fp.set_preference("network.proxy.type", 1)
    fp.set_preference("network.proxy.http",PROXY_HOST)
    fp.set_preference("network.proxy.http_port",int(PROXY_PORT))
    fp.set_preference("network.proxy.https",PROXY_HOST)
    fp.set_preference("network.proxy.https_port",int(PROXY_PORT))
    fp.set_preference("network.proxy.ssl",PROXY_HOST)
    fp.set_preference("network.proxy.ssl_port",int(PROXY_PORT))  
    fp.set_preference("network.proxy.ftp",PROXY_HOST)
    fp.set_preference("network.proxy.ftp_port",int(PROXY_PORT))   
    fp.set_preference("network.proxy.socks",PROXY_HOST)
    fp.set_preference("network.proxy.socks_port",int(PROXY_PORT))   
    fp.set_preference("general.useragent.override","Mozilla/5.0 (Macintosh; Intel Mac OS X 10_9_3) AppleWebKit/537.75.14 (KHTML, like Gecko) Version/7.0.3 Safari/7046A194A")
    fp.update_preferences()
    return webdriver.Firefox(firefox_profile=fp)

problem is , when i run it IDLE frozen and cant take commands for seconds then i get this Error :

An exception was raised, which tells you to that a socksVersion was expected, try for example:

fp.set_preference("network.proxy.socksVersion", 1)
