using http proxy with selenium Geckodriver

Question

I tried a few things but non of them worked. Anyone have a working example of using a HTTP proxy with Geckodriver for Selenium 3? I am using Java bindings

Here is what I tried

        DesiredCapabilities capabilities = DesiredCapabilities.firefox();
        Proxy proxy = new Proxy();
        proxy.setHttpProxy("proxyip:proxyport");
        capabilities.setCapability("proxy", proxy);

        System.setProperty("webdriver.gecko.driver", "C:\\geckodriver-v0.16.1-win64\\geckodriver.exe");
        WebDriver driver = new FirefoxDriver(capabilities);

Probably that's because you `DesiredCapabilities.chrome()` but next you have used `geckodriver.exe` in system.property — undetected Selenium, May 14 '17 at 06:13
@Dev I tried it with firefox I still get an exception https://pastebin.com/YSt3626w — Arya, May 14 '17 at 06:17
Okay, in the error stacktrace I can see `SessionNotCreatedException` exception which means that the marionatte is not even called. Is Firefox opening up through driver on your box? — undetected Selenium, May 14 '17 at 06:29
yes firefox opens but does not load the page. If I don't pass it capabilities, then it will also load the page and I can interact with it. — Arya, May 14 '17 at 06:33

To enable proxy with Firefox browser you need to create a new profile and pass it to the driver as follows:

Setting up HTTP proxy:

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);

Setting up SSL proxy:

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

```profile.setPreference("network.proxy.ssl", "localhost"); profile.setPreference("network.proxy.ssl_port", 3128);``` – Leblanc Meneses Feb 06 '18 at 15:10
This didn't work for me with the latest Firefox and Geckodriver as of today, but the method prescribed by the official docs worked: https://www.selenium.dev/documentation/en/webdriver/http_proxies/ – Motin Mar 29 '21 at 06:12
@Motin, those docs only describe Chrome. How did you get it working with Firefox? – Nikki Jan 28 '22 at 18:30

If you need to use a proxy with authorization, then selenium will not be able to do it. Since selenium does not support working with alerts asking for a password. I wrote an add-on for Firefox with which you can solve both the problem with the proxy and with cookies and headers.

You can use an add-on from the releases directory, it is already signed
