Learning Selenium is this code:

print ("Enter the name without .txt")
TXTER = INPUT ("Enter where to take passwords and logins and so on:")
TXT = TXTER + '. TXT'
F = OPEN (TXT)
User_Agent = F.ReadLine ()
If User_Agent == "\ n":
  Print ("Enter User-Agent to File")
ELSE:
  Print (")
  ninja = user_Agent
proxy_host = f.ReadLine ()
if proxy_host == "\ n":
  Print ("It seems I have to work without a proxy ...")
  Option = WebDriver.firefoxoptions ()
  option.set_preference ("Dom.WebDriver.Enabled", False)
  option.set_preference ("general.useragent.Ordride", Ninja)
  Driver = WebDriver.Firefox (options = option)
ELSE:
  Print ("It seems I have to work with a proxy ...")
  proxy_port = F.ReadLine ()
  proxy_login = F.ReadLine ()
  proxy_password = F.ReadLine ()
  IF proxy_login == "\ n":
    Print ("It seems no login from proxy ...")
    Print ("Do not advise you to use free proxy!")
    if proxy_password == "\ n":
      Print ("It seems no password from proxy ...")
      Proxy_Host = proxy_Host.
      Proxy_Port = proxy_port.
      FP = WebDriver.firefoxProfile ()
      FP.SET_PREFERENCE ('Network.Proxy.Type', 1)
      FP.SET_PREFERENCE ('Network.Proxy.http', Proxy_Host)
      FP.SET_PREFERENCE ('Network.Proxy.http_port', Proxy_Port)
      FP.Set_Preference ('Network.Proxy.https', Proxy_Host)
      FP.Set_Preference ('Network.Proxy.https_PORT', Proxy_Port)
      FP.Set_Preference ('Network.Proxy.ftp', Proxy_Host)
      FP.Set_Preference ('Network.Proxy.ftp_Port', Proxy_Port)
      FP.SET_PREFERENCE ('Network.Proxy.ssl', Proxy_Host)
      FP.SET_PREFERENCE ('Network.Proxy.ssl_Port', Proxy_Port)
      FP.Set_Preference ('Network.Proxy.no_Proxies_on', '')
      Option = WebDriver.firefoxoptions ()
      option.set_preference ("Dom.WebDriver.Enabled", False)
      option.set_preference ("general.useragent.Ordride", Ninja)
      Driver = WebDriver.firefox (options = option, Firefox_Profile = Fp)
    ELSE:
      Print ("Something is wrong here!")
      sys.exit ()
  ELSE:
    proxy_options = {
      "Proxy": {
        "https": f "http: // {proxy_login}: {proxy_password} @" + proxy_host + ":" + proxy_port
      }
    }
    Option = WebDriver.firefoxoptions ()
    option.set_preference ("Dom.WebDriver.Enabled", False)
    option.set_preference ("general.useragent.Ordride", Ninja)
    Driver = WebDriver.firefox (options = option, seleniumwire_options = proxy_options)
    Print ("OK")
    Driver.get ('https://browser-info.ru/')

When moving, writes this:

And in CMD writes:

Answer 1, Authority 100%

It will not be possible to log in to the proxy. And try to fill the alert with authorization either will not work because not supported.

The only thing that can help is seleniumwire.

$: pip install selenium-wire

from seleniumwire import webdriver
Options = {
  'proxy': {
    'http': 'http: // user: [email protected]: 8888',
    'https': 'http: // user: [email protected]: 8888',
    'NO_PROXY': 'Localhost, 127.0.0.1'
  }
}
Driver = WebDriver.firefox (SeleniumWire_Options = Options)
Driver.get ("https://whoer.net")

p.s. Or wait a few days. I just finish the addition so that you can put a proxy with authorization and cookies. But this is not exactly)

Answer 2

Only one thing was helped to remove the User-Agent substitution or a random selection of Iery like this:

user_list = ["Mozilla / 4.0 (compatible; MSIE 7.0; Windows NT 6.0; Trident / 4.0)", " Mozilla / 4.0 (Compatible; MSIE 7.0; Windows NT 6.1; Trident / 7.0; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; MATP; MATP) "," Mozilla / 5.0 (compatible; MSIE 10.0; Windows NT 6.1; WOW64; TRIDENT / 6.0) "]
Ninja = Random.Choice (User_List)
Print (Ninja)
Option = WebDriver.firefoxoptions ()
option.set_preference ("Dom.WebDriver.Enabled", False)
option.set_preference ("general.useragent.Ordride", Ninja)
Driver = WebDriver.Firefox (options = option)
Driver.get ('https://browser-info.ru/')

You can also still be like this:

ninja = "'" + user-agent + "'"
