Python Selenium Webdriver - Changing proxy settings on the fly

Question

I\'m currently successfully using the code below to use a proxy with the Selenium webdriver. Unfortunately, I can\'t seem to make it change the proxy settings without restar

Answer 1

To set a proxy on the fly with Firefox:

def set_proxy(driver, http_addr='', http_port=0, ssl_addr='', ssl_port=0, socks_addr='', socks_port=0):

    driver.execute("SET_CONTEXT", {"context": "chrome"})

    try:
        driver.execute_script("""
          Services.prefs.setIntPref('network.proxy.type', 1);
          Services.prefs.setCharPref("network.proxy.http", arguments[0]);
          Services.prefs.setIntPref("network.proxy.http_port", arguments[1]);
          Services.prefs.setCharPref("network.proxy.ssl", arguments[2]);
          Services.prefs.setIntPref("network.proxy.ssl_port", arguments[3]);
          Services.prefs.setCharPref('network.proxy.socks', arguments[4]);
          Services.prefs.setIntPref('network.proxy.socks_port', arguments[5]);
          """, http_addr, http_port, ssl_addr, ssl_port, socks_addr, socks_port)

    finally:
        driver.execute("SET_CONTEXT", {"context": "content"})

Usage:

 driver = webdriver.Firefox()

 set_proxy(driver, http_addr="212.35.56.21", http_port=8080)

 driver.get("http://....")

 set_proxy(driver, http_addr="212.35.56.22", http_port=8888)

 driver.get("http://....")
