Capabilities specific to Firefox browser

These capabilities are specific to Firefox.

Define Capabilities using FirefoxOptions

FirefoxOptions is the new way to define capabilities for the Firefox browser and should generally be used in preference to DesiredCapabilities.

FirefoxOptions options = new FirefoxOptions();
options.addPreference("network.proxy.type", 0);
driver = new RemoteWebDriver(options);
  
from selenium.webdriver.firefox.options import Options
options = Options()
options.headless = True
driver = webdriver.Firefox(options=options)
  
var options = new FirefoxOptions();
options.Proxy.Kind = ProxyKind.Direct;
var driver = new FirefoxDriver(options);
  
require 'selenium-webdriver'
opts = Selenium::WebDriver::Firefox::Options.new(args: ['-headless'])
driver = Selenium::WebDriver.for(:firefox, options: opts)
  
const { Builder } = require("selenium-webdriver");
const firefox = require('selenium-webdriver/firefox');

const options = new firefox.Options();
options.headless();
const driver = new Builder()
    .forBrowser('firefox')
    .setFirefoxOptions(options)
    .build();
  

val options = new FirefoxOptions()
options.addPreference("network.proxy.type", 0)
driver = RemoteWebDriver(options)

Setting a custom profile

It is possible to create a custom profile for Firefox as demonstrated below.

FirefoxProfile profile = new FirefoxProfile();
FirefoxOptions options = new FirefoxOptions();
options.setProfile(profile);
driver = new RemoteWebDriver(options);
  
from selenium.webdriver.firefox.options import Options
from selenium.webdriver.firefox.firefox_profile import FirefoxProfile
options=Options()
firefox_profile = FirefoxProfile()
firefox_profile.set_preference("javascript.enabled", False)
options.profile = firefox_profile
  
var options = new FirefoxOptions();
var profile = new FirefoxProfile();
options.Profile = profile;
var driver = new RemoteWebDriver(options);
  
profile = Selenium::WebDriver::Firefox::Profile.new
profile['browser.download.dir'] = "/tmp/webdriver-downloads"
options = Selenium::WebDriver::Firefox::Options.new(profile: profile)
driver = Selenium::WebDriver.for :firefox, options: options
  
const { Builder } = require("selenium-webdriver");
const firefox = require('selenium-webdriver/firefox');

const options = new firefox.Options();
let profile = '/path to custom profile';
options.setProfile(profile);
const driver = new Builder()
    .forBrowser('firefox')
    .setFirefoxOptions(options)
    .build();
  

val options = FirefoxOptions()
options.profile = FirefoxProfile()
driver = RemoteWebDriver(options)
