How To Set Proxy In Firefox Using Selenium Webdriver
How to set Proxy in Firefox using Selenium WebDriver?
Internet bandwidth is an important asset, especially at workplaces where multiple resources use the same network simultaneously. High-speed internet enables work to be completely faster and more efficiently. This is particularly true when working with web applications, where the internet is actively tting up Proxy Servers makes the system faster by compressing traffic, managing cache data, and frequently visited web pages. This enhances internet speed and decreases page load speed proxy server is an entity between the client and the server. Whenever placing requests, the entire traffic from the server flows to the client via the proxy server. Setting up the proxy server while testing a web application on Selenium WebDriver could be helpful in capturing servers let the user access the URL of the web application for testing, despite the complex topologies of the network. This network at the workplace complies with the strict policies and thus has many restrictions that hinders testing web applications on could also mock the backend request calls made by the web application under test, which could be useful in the testing running a Selenium test, it is essential to set the proxy settings of the browser, since the WebDriver launches the browser all over again, every time a test is run. However, each time the browser is launched, the proxy settings reset automatically and need to be reset every article discusses the various methods by which to manage proxy settings in Selenium tting up Firefox Proxy using SeleniumThere are two ways of setting up Firefox Proxy using Selenium:By adding preferred Proxy Server Host and Port details to FirefoxOptions class, that can be later used in the setting Firefox Profile using FirefoxProfile setting up desired capabilities. 1. Using FirefoxOptions ClassThe following code sets up Proxy by using Class FirefoxOptions:import;
import;
public class proxyTest {
public static void main(String[] args) {
Proxy proxy = new Proxy();
//Adding the desired host and port for the, ssl, and ftp Proxy Servers respectively
tHttpProxy(“
tSslProxy(“
tFtpProxy(“
FirefoxOptions options = new FirefoxOptions();
tCapability(“proxy”, proxy);
//Calling new Firefox profile for test
WebDriver driver = new FirefoxDriver(options);
(“);
()(). maximize();
();}}2. Using FirefoxProfile ClassSimilar to the previous method, one can also set Firefox Proxy in Selenium using FirefoxProfile Class. Use the code below to do it:import;
FirefoxProfile profile = new FirefoxProfile();
tProxyPreferences(proxy);
WebDriver driver = new FirefoxDriver(profile);
();}}Also Read: How to set a proxy in Chrome using Selenium3. Using Desired CapabilitiesSimilarly one can also set Proxy in Firefox using Selenium Webdriver, through its desired;

tCapability(, proxy);
WebDriver driver = new FirefoxDriver(dc);

Webdriver and proxy server for firefox – Stack Overflow
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.
asked May 22 ’10 at 11:58
Value for should be integer (no quotes should be used) and should be set as 1 (, Manual proxy settings)
FirefoxProfile profile = new FirefoxProfile();
tPreference(“”, 1);
tPreference(“”, “localhost”);
tPreference(“”, 3128);
WebDriver driver = new FirefoxDriver(profile);

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:
tPreference(“”, “”);
tPreference(“”, 8080);
driver = new FirefoxDriver(profile);
Gotchas here: enter just the domain and not, the property name is and not
I’m now having even more fun trying to get it to accept my self signed certificates…

Look at the documentation page.
Tweaking an existing Firefox profile
You need to change “” & “” profile settings.
dAdditionalPreference(“”, “localhost”);
dAdditionalPreference(“”, “3128”);

Just to add to the above given solutions.,
Adding the list of possibilities (integer values) for the “”.
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 “” value should be set as mentioned below.

The WebDriver API has been changed. The current snippet for setting the proxy is
tPreference(“”, “3128”);

In case if you have an autoconfig URL –
FirefoxProfile firefoxProfile = new FirefoxProfile();
tPreference(“”, 2);
tPreference(“”, “);
WebDriver driver = new FirefoxDriver(firefoxProfile);

Here’s a java example using DesiredCapabilities. I used it for pumping selenium tests into jmeter. (was only interested in HTTP requests)
import;
String myProxy = “localhost:7777”; //example: proxy host=localhost port=7777
DesiredCapabilities capabilities = new DesiredCapabilities();
tCapability(,
new Proxy(). setHttpProxy(myProxy));
WebDriver webDriver = new FirefoxDriver(capabilities);

For PAC based urls
Proxy proxy = new Proxy();
tProxyType();
tProxyAutoconfigUrl(“some-server/”);
tCapability(, proxy);
return new FirefoxDriver(capabilities);
I hope this could help.

According to the latest documentation
from selenium import webdriver
PROXY = “
REFOX[‘proxy’] = {
“Proxy”: PROXY,
“ftpProxy”: PROXY,
“sslProxy”: PROXY,
“proxyType”: “MANUAL”, }
with refox() as driver:

Firefox Proxy: JAVA
String PROXY = “localhost:8080”;
proxy = new ();
tHttpProxy(PROXY)setFtpProxy(PROXY). setSslProxy(PROXY);
DesiredCapabilities cap = new DesiredCapabilities();
WebDriver driver = new FirefoxDriver(cap);

There is another solution, i looked for because a had problems with code like this (it s set the system proxy in firefox):
tPreference(“”, “8080”);
I prefer this solution, it force the proxy manual setting in firefox.
To do that, use the object to setup Firefox:
tHttpProxy(“localhost:8080”);
tProxyPreferences(localhostProxy);
if it could help…

String PROXY = “”;
tpProxy=PROXY;
proxy. FtpProxy=PROXY;
lProxy=PROXY;
tProxyPreferences(proxy);
FirefoxDriver driver = new FirefoxDriver(profile);
It is for C#

How to Configure a Proxy Server in Firefox – HowToGeek
If you want to send your web browser traffic—and only your browser traffic—through a proxy, Mozilla Firefox is a great option. It uses your system-wide proxy settings by default, but you can configure separate proxy settings for Firefox only.
RELATED: What’s the Difference Between a VPN and a Proxy?
Generally, you’ll use a proxy if your school or work provides it to you. You could also use a proxy to hide your IP address or access geoblocked websites that aren’t available in your country, but we recommend a VPN for that instead. If you need to set up a proxy for school or work, get the necessary credentials from them and read on.
Firefox is unique here because Chrome, Edge, and Internet Explorer don’t allow you to set a custom proxy server. They only use your system-wide proxy settings. With Firefox, you can route only some web traffic through the proxy without using it for every application on your system.
To access proxy settings in Mozilla Firefox, click on Firefox’s menu and go to Options.
Click the “Advanced” icon at the left side of the Preferences window, click the “Network” tab at the top of the window, and then click the “Settings” button under Connection.
You can select four different proxy options here. By default, Firefox is set to “Use system proxy settings”.
No proxy: Firefox won’t use a proxy server, even if one is configured in your system-wide proxy settings.
Auto-detect proxy settings for this network: Firefox will use the Web Proxy Auto-Discovery Protocol, also known as WPAD, to detect the appropriate proxy for your network. This feature is sometimes used only on business and educational networks to automatically provide the necessary proxy settings to all PCs on a network.
Use system proxy settings: Firefox follows whatever proxy settings you have configured in your system settings. If you don’t have a system-wide proxy configured, Firefox won’t use a proxy.
Manual proxy configuration: Firefox allows you to manually set custom proxy settings that will only be used for Firefox itself.
If you select “Manual proxy configuration”, you’ll need to enter your proxy server settings in the boxes here. Your proxy service provider—or employer, if it’s provided by your employer—will be able to provide the settings you need.
Enter the address of the proxy server you want to use for normal, unencrypted HTTP browsing connections in the “HTTP Proxy” box. You’ll also need to enter the port the proxy server uses in the “Port” box.
You’ll usually want to click the “Use the proxy server for all protocols” option. Firefox will also use your HTTP proxy server for SSL-encrypted HTTPS connections and File Transfer Protocol (FTP) connections.
Uncheck this box if you want to enter separate proxy servers for HTTP, HTTPS, and FTP connections. This isn’t common.
If you’re configuring a SOCKS proxy, leave the HTTP Proxy, SSL Proxy, and FTP Proxy boxes empty. Enter the address of the SOCKS proxy into the “SOCKS Host” and its port into the “Port” box.
RELATED: How to Use SSH Tunneling to Access Restricted Servers and Browse Securely
When you’re hosting a SOCKS proxy on your local PC, you’ll need to enter 127. 0. 1 and the port the SOCKS proxy is listening on. For example, you’ll need to do this if you create an SSH tunnel using dynamic port forwarding and want to send your browsing traffic through it. Firefox will send your browsing activity through the proxy server running on your local computer.
By default, Firefox uses SOCKS v5 for the connection. Select SOCKS v4 if your SOCKS proxy uses the older standard instead. If you’re not sure, leave the option set to SOCKS v5.
Firefox also allows you to provide a list of addresses that it will bypass the proxy for. Enter these in the “No Proxy for” box. By default, the list here includes localhost and 127. 1. These addresses both point to your local PC itself. When you attempt to access a web server running on your PC, Firefox will access it directly rather than attempting to access the addresses through the proxy.
You can add other domain names and IP addresses to this list. Just separate each address in the list with a comma followed by a space. For example, if you want Firefox to access directly instead of accessing through the proxy, you’d add to the end of the list like so:
localhost, 127. 1,
If Firefox can’t access the proxy sever you configure—for example, if the proxy server is down, if your Internet connection is down, or if you entered the details incorrectly—you’ll see an “Unable to find the proxy server” error message when you attempt to access a website.
You’ll need to go back into Firefox’s proxy server settings and either disable the proxy or fix your proxy settings to browse the web.
