Set userAgent with selenium-webdriver/firefox (NodeJS)

Question

I have a code running browser using 'selenium-webdriver'. It runs on Ubuntu.

I have to override userAgent so it will look like the requests from the browser are coming from Windows (ie the value of User-Agent requests' header).

Here is my NodeJS code:

var firefox = require('selenium-webdriver/firefox');

var profile = new firefox.Profile();
profile.setPreference('general.useragent.override', 'Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/53.0.2785.143 Safari/537.36');

var options = new firefox.Options().setProfile(profile);
console.log(profile);
var driver = new firefox.Driver(options);

driver.get('http://whatsmyuseragent.com/');

The userAgent that appears is

Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:49.0) Gecko/20100101 Firefox/49.0

Here is the console.log(profile); output (as you can see - 'general.useragent.override': 'Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/53.0.2785.143 Safari/537.36' appears there, but doesn't effect the browser settings):

  nativeEventsEnabled_: true,
  template_: undefined,

  extensions_: [] }

I tried to set the general.useragent.override manually (following http://www.howtogeek.com/113439/how-to-change-your-browsers-user-agent-without-installing-any-extensions/ ) - it works! Though it doesn't effect the settings of the instances that are opened with selenium-webdriver driver (anyway I prefer to be able to set it pragmatically).

Any idea why doesn't it work for me?

Answer 1

As far as I know the user Agent can't be set programatically with firefox . Instead I suggest you to use chromium with the ChromeDriver . As the following python example shows you can easily set the User Agent to your desired value.

from selenium import webdriver

from selenium.webdriver.chrome.options import Options

chrome_options = Options()
chrome_options.add_argument('--user-agent=\"Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/53.0.2785.143 Safari/537.36\"')
driver = webdriver.Chrome(chrome_options=chrome_options)

driver.get('https://www.whatsmyua.info/')

If you want to change your userAgent during runtime of your script you will need to start a new driver instance.

    var nVer = navigator.appVersion;
    var nAgt = navigator.userAgent;
    var browser = navigator.appName;
    var version = '' + parseFloat(navigator.appVersion);
    var majorVersion = parseInt(navigator.appVersion, 10);
    var nameOffset, verOffset, ix;
