[firefox] Webdriver and proxy server for firefox

are there any ways to set firefox's proxy settings? I found here information about FoxyProxy but when Selenium works, plugins are unactivated in window.

According to the latest documentation

from selenium import webdriver

PROXY = "<HOST:PORT>"
webdriver.DesiredCapabilities.FIREFOX['proxy'] = {
    "httpProxy": PROXY,
    "ftpProxy": PROXY,
    "sslProxy": PROXY,
    "proxyType": "MANUAL",

}

with webdriver.Firefox() as driver:
    # Open URL
    driver.get("https://selenium.dev")

Here's a java example using DesiredCapabilities. I used it for pumping selenium tests into jmeter. (was only interested in HTTP requests)

import org.openqa.selenium.Proxy;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.remote.CapabilityType;
import org.openqa.selenium.remote.DesiredCapabilities;

String myProxy = "localhost:7777";  //example: proxy host=localhost port=7777
DesiredCapabilities capabilities = new DesiredCapabilities();
capabilities.setCapability(CapabilityType.PROXY,
                           new Proxy().setHttpProxy(myProxy));
WebDriver webDriver = new FirefoxDriver(capabilities); 

Value for network.proxy.http_port should be integer (no quotes should be used) and network.proxy.type should be set as 1 (ProxyType.MANUAL, Manual proxy settings)

FirefoxProfile profile = new FirefoxProfile();
profile.setPreference("network.proxy.type", 1);
profile.setPreference("network.proxy.http", "localhost");
profile.setPreference("network.proxy.http_port", 3128);
WebDriver driver = new FirefoxDriver(profile);

Just to add to the above given solutions.,

Adding the list of possibilities (integer values) for the "network.proxy.type".

0 - Direct connection (or) no proxy. 

1 - Manual proxy configuration

2 - Proxy auto-configuration (PAC).

4 - Auto-detect proxy settings.

5 - Use system proxy settings. 

So, Based on our requirement, the "network.proxy.type" value should be set as mentioned below.

FirefoxProfile profile = new FirefoxProfile();
profile.setPreference("network.proxy.type", 1);
WebDriver driver = new FirefoxDriver(profile);

The WebDriver API has been changed. The current snippet for setting the proxy is

FirefoxProfile profile = new FirefoxProfile();
profile.setPreference("network.proxy.http", "localhost");
profile.setPreference("network.proxy.http_port", "3128");
WebDriver driver = new FirefoxDriver(profile);

There is another solution, i looked for because a had problems with code like this (it s set the system proxy in firefox):

FirefoxProfile profile = new FirefoxProfile();
profile.setPreference("network.proxy.http", "localhost");
profile.setPreference("network.proxy.http_port", "8080");
driver = new FirefoxDriver(profile);

I prefer this solution, it force the proxy manual setting in firefox. To do that, use the org.openqa.selenium.Proxy object to setup Firefox :

FirefoxProfile profile = new FirefoxProfile();
localhostProxy.setProxyType(Proxy.ProxyType.MANUAL);
localhostProxy.setHttpProxy("localhost:8080");
profile.setProxyPreferences(localhostProxy);
driver = new FirefoxDriver(profile);

if it could help...

FirefoxProfile profile = new FirefoxProfile();
String PROXY = "xx.xx.xx.xx:xx";
OpenQA.Selenium.Proxy proxy = new OpenQA.Selenium.Proxy();
proxy.HttpProxy=PROXY;
proxy.FtpProxy=PROXY;
proxy.SslProxy=PROXY;
profile.SetProxyPreferences(proxy);
FirefoxDriver driver = new FirefoxDriver(profile);

It is for C#

I just had fun with this issue for a couple of days and it was hard for me to find an answer for HTTPS, so here's my take, for Java:

    FirefoxProfile profile = new FirefoxProfile();
    profile.setPreference("network.proxy.type", 1);
    profile.setPreference("network.proxy.http", "proxy.domain.example.com");
    profile.setPreference("network.proxy.http_port", 8080);
    profile.setPreference("network.proxy.ssl", "proxy.domain.example.com");
    profile.setPreference("network.proxy.ssl_port", 8080);
    driver = new FirefoxDriver(profile);

Gotchas here: enter just the domain and not http://proxy.domain.example.com, the property name is .ssl and not .https

I'm now having even more fun trying to get it to accept my self signed certificates...

Firefox Proxy: JAVA

String PROXY = "localhost:8080";

org.openqa.selenium.Proxy proxy = new org.openqa.selenium.Proxy();

proxy.setHttpProxy(PROXY)setFtpProxy(PROXY).setSslProxy(PROXY);

DesiredCapabilities cap = new DesiredCapabilities();

cap.setCapability(CapabilityType.PROXY, proxy); 

WebDriver driver = new FirefoxDriver(cap);

In case if you have an autoconfig URL -

        FirefoxProfile firefoxProfile = new FirefoxProfile();
        firefoxProfile.setPreference("network.proxy.type", 2);
        firefoxProfile.setPreference("network.proxy.autoconfig_url", "http://www.etc.com/wpad.dat");
        firefoxProfile.setPreference("network.proxy.no_proxies_on", "localhost");
        WebDriver driver = new FirefoxDriver(firefoxProfile);

Preferences -> Advanced -> Network -> Connection (Configure how Firefox connects to the Internet)

For PAC based urls

 Proxy proxy = new Proxy();
 proxy.setProxyType(Proxy.ProxyType.PAC);
 proxy.setProxyAutoconfigUrl("http://some-server/staging.pac");
 DesiredCapabilities capabilities = new DesiredCapabilities();
 capabilities.setCapability(CapabilityType.PROXY, proxy);
 return new FirefoxDriver(capabilities);

I hope this could help.
