Selenium Firefox not adding extensions

I'm trying to get ublock installed on Firefox with Selenium. The problem is, the extension won't load. The browser loads fine but does not add the extension.
FirefoxProfile profile = new FirefoxProfile();
profile.AddExtension("ublock_origin-1.17.4-an+fx.xpi");
FirefoxOptions options = new FirefoxOptions
{
Profile = profile
};
IWebDriver driver = new FirefoxDriver(options);
I've seen this but I don't want to use an old version of firefox, and i haven't seen any other fix for it.
Currently using v0.23.0 of geckodriver for win64.
How can I add extensions to firefox with selenium? (without using an old version)

Try splitting out the options part, see if that makes a difference:
FirefoxProfile profile = new FirefoxProfile();
profile.AddExtension(*file path*);
FirefoxOptions options = new FirefoxOptions();
options.Profile = profile;
IWebDriver driver = new FirefoxDriver(options);

FirefoxProfile profile = new FirefoxProfile();
FirefoxOptions options = new FirefoxOptions
{
Profile = profile
};
IWebDriver driver = new FirefoxDriver(options);
firefoxDriver.InstallAddOnFromFile("ublock_origin-1.17.4-an+fx.xpi"); // Dear Wizard, this is the magic
Use Selenium 4.X and use the FirefoxDriver.InstallAddOnFromFile method instead of the the FirefoxOptions.AddExtension

DesiredCapabilities is obsolete in Selenium Web Driver V.3.14 How to write the code for Selenium grid in C#?

I have the following code. I update the selenium web driver to v3.14 and it shows the obsolete and error messages.
DesiredCapabilities capabilities; --deprecated
capabilities = DesiredCapabilities.Chrome(); --has the error for Selennium wen driver v3.14
capabilities.SetCapability(CapabilityType.Platform, new Platform(PlatformType.Windows));
Uri uri = new Uri(hub url);
_driver = new RemoteWebDriver(uri, capabilities, TimeSpan.FromSeconds(120));
From class RemoteWebDriver in OpenQA.Selenium.Remote, it still has the ICapabilities parameter
public RemoteWebDriver(Uri remoteAddress, ICapabilities desiredCapabilities, TimeSpan commandTimeout);
I saw some posts using Chrome options. But I still cannot make it work for selenium grid. Any idea?

The following should work without incident:
ChromeOptions options = new ChromeOptions();
options.PlatformName = "windows";
Uri uri = new Uri(hub url);
_driver = new RemoteWebDriver(uri, options.ToCapabilities(), TimeSpan.FromSeconds(120));

How to start ChromeDriver in headless mode

I want to try out headless chrome, but I am running into this issue, that I can't start the driver in headless mode. I was following google documentation. am I missing something ? The code execution gets stuck in var browser = new ChromeDriver(); line
Here is my code:
var chromeOptions = new ChromeOptions
{
BinaryLocation = #"C:\Users\2-as Aukstas\Documents\Visual Studio 2017\Projects\ChromeTest\ChromeTest\bin\Debug\chromedriver.exe",
DebuggerAddress = "localhost:9222"
};
chromeOptions.AddArguments(new List<string>() {"headless", "disable-gpu" });
var browser = new ChromeDriver(chromeOptions);
browser.Navigate().GoToUrl("https://stackoverflow.com/");
Console.WriteLine(browser.FindElement(By.CssSelector("#h-top-questions")).Text);

UPDATE
Chrome version 60 is out so all you need to do is to download Chromdriver and Selenium via Nuget and use this simple code and everything works like a charm. Amazing.
using OpenQA.Selenium;
using OpenQA.Selenium.Chrome;
...
var chromeOptions = new ChromeOptions();
chromeOptions.AddArguments("headless");
using (var browser = new ChromeDriver(chromeOptions))
{
// add your code here
}
DATED
There is a solution until the official release of Chrome 60 will be released. You can download Chrome Canary and use headless with it. After installation set BinaryLocation to point to chrome canary also comment out the DebuggerAddress line(it forces chrome to timeout):
var chromeOptions = new ChromeOptions
{
BinaryLocation = #"C:\Users\2-as Aukstas\AppData\Local\Google\Chrome SxS\Application\chrome.exe",
//DebuggerAddress = "127.0.0.1:9222"
};
chromeOptions.AddArguments(new List<string>() { "no-sandbox", "headless", "disable-gpu" });
var _driver = new ChromeDriver(chromeOptions);

For you that did not get reference for ChromeDriver.
Use this step :
Download the dll from this: http://seleniumtestings.com/selenium-download/
Extract, and you should see: Selenium.WebDriverBackedSelenium.dll, ThoughtWorks.Selenium.Core.dll, WebDriver.dll and WebDriver.Support.dll
Add those files via "Add Reference"
Now you can use it:
String url = "http://www.google.com";
var chromeOptions = new ChromeOptions();
chromeOptions.AddArguments(new List<string>() {
"--silent-launch",
"--no-startup-window",
"no-sandbox",
"headless",});
var chromeDriverService = ChromeDriverService.CreateDefaultService();
chromeDriverService.HideCommandPromptWindow = true; // This is to hidden the console.
ChromeDriver driver = new ChromeDriver(chromeDriverService, chromeOptions);
driver.Navigate().GoToUrl(url);
====
If after you run, you are still facing error about no ChromeDriver.exe file, try to add the Selenium.WebDriver.ChromeDriver, WebDriver.ChromeDriver, WebDriver.ChromeDriver.win32, Selenium.Chrome.WebDriver via nuget.

As alternative:
Add 2 libraries via NuGet like below picture.
Try below Code:
String url = "http://www.google.com";
var chromeOptions = new ChromeOptions();
chromeOptions.AddArguments(new List<string>() { "headless" });
var chromeDriverService = ChromeDriverService.CreateDefaultService();
ChromeDriver driver = new ChromeDriver(chromeDriverService, chromeOptions);
driver.Navigate().GoToUrl(url);

What OS you're running? I see on developers.google.com/web/updates/2017/04/headless-chrome that headless won't be available on Windows until Chrome 60.

Below i have given how to set the headless to true for firefox and chrome browsers.
FirefoxOptions ffopt = new FirefoxOptions();
FirefoxOptions option = ffopt.setHeadless(true);
WebDriver driver = new FirefoxDriver(option);
ChromeOptions coptions = new ChromeOptions();
ChromeOptions options = coptions.setHeadless(true);
WebDriver driver = new ChromeDriver(options);

How to set up Selenium and ChromeDriver to run in headless mode

I am trying to run a browser test using xUnit, Selenium, and Chrome Canary (headless mode) but I keep getting this error:
OpenQA.Selenium.WebDriverException
The HTTP request to the remote WebDriver server for URL
http://localhost:58692/session timed out after 60 seconds.
Here's my code:
var chromeOptions = new ChromeOptions
{
BinaryLocation = #"C:\Users\<USERNAME>\AppData\Local\Google\Chrome SxS\Application\chrome.exe",
DebuggerAddress = "127.0.0.1:9222"
};
chromeOptions.AddArguments("no-sandbox", "headless", "disable-gpu");
_driver = new ChromeDriver(chromeOptions) {Url = Url};
I'm quite new to C# so I'm not sure if I'm doing something blatantly wrong, or if I'm just missing a setting. Googling the above error told me that I need to set the debugger address and use the no-sandbox flag, but neither seem to be helping.
Using these versions:
selenium 3.4
chromedriver 2.29
xunit 2.2

Taking out the debugger address made it work.
var chromeOptions = new ChromeOptions
{
BinaryLocation = #"C:\Users\<USERNAME>\AppData\Local\Google\Chrome SxS\Application\chrome.exe",
};

In case that others will get here while googling...
What worked for me was to download the latest chrome-driver from this link:
https://sites.google.com/a/chromium.org/chromedriver/downloads
Happy coding :)

case "chrome9515headless":
ChromeOptions chromeOptions = new ChromeOptions();
chromeOptions.AddArgument("--headless");
chromeOptions.AddArgument("--disable-gpu");
chromeOptions.AddArgument("--disable-infobars");
chromeOptions.AddArgument("--disable-extensions");
chromeOptions.AddArgument("--window-size=1200,900");
chromeOptions.AddArgument("--disable-browser-side-navigation");
webDriver = new RemoteWebDriver(new Uri("http://127.0.0.1:9515"),
chromeOptions.ToCapabilities());
break;
case "chrome9515canary":
ChromeOptions chromeOptionsCanary = new ChromeOptions();
chromeOptionsCanary.BinaryLocation= #"C:\Users\********\AppData\Local\Google\Chrome SxS\Application\chrome.exe";
//chromeOptionsCanary.AddArgument("--headless");
//chromeOptions.AddArgument("--disable-gpu");
chromeOptionsCanary.AddArgument("--disable-infobars");
chromeOptionsCanary.AddArgument("--disable-extensions");
chromeOptionsCanary.AddArgument("--window-size=1200,900");
chromeOptionsCanary.AddArgument("--disable-browser-side-navigation");
webDriver = new RemoteWebDriver(new Uri("http://127.0.0.1:9515"),
chromeOptionsCanary.ToCapabilities());
break;

How can I add profile preferences to Chrome for Selenium Grid 2 in C#?

This is how I add profile preferences to Chrome for Local Auto-test runs and TeamCity(CI):
Capabilities = DesiredCapabilities.Chrome();
var chromeOptions = new ChromeOptionsWithPrefs();
chromeOptions.AddUserProfilePreference("download.default_directory", DownloadPath);
chromeOptions.AddUserProfilePreference("intl.accept_languages", "nl");
chromeOptions.AddUserProfilePreference("disable-popup-blocking", "true");
return new ChromeDriver(chromeDriverPath, chromeOptions);
But when I create new 'RemoteWebDriver', I must send it a hub URL and 'Capabilities', this way I send profile preferences to Firefox (to RemoteWebDriver):
var profile = new FirefoxProfile();
Capabilities = DesiredCapabilities.Firefox();
profile.SetPreference("browser.helperApps.alwaysAsk.force", false);
profile.SetPreference("browser.download.useDownloadDir", true);
profile.SetPreference("browser.download.folderList", 2);
profile.SetPreference("browser.download.dir", DownloadPath);
profile.SetPreference("browser.helperApps.neverAsk.saveToDisk",
"application/zip, application/octet-stream");
Capabilities.SetCapability(FirefoxDriver.ProfileCapabilityName, profile.ToBase64String());
return Capabilities;
Can someone help me, I need to do the same thing to Chrome as I did to Firefox. Basically what I need, is that I could change the default path for downloading files.

You'll want to do something like the following:
var chromeOptions = new ChromeOptions();
chromeOptions.AddUserProfilePreference("download.default_directory", DownloadPath);
chromeOptions.AddUserProfilePreference("intl.accept_languages", "nl");
chromeOptions.AddUserProfilePreference("disable-popup-blocking", "true");
IWebDriver driver = new RemoteWebDriver(new Uri("http://path/to/selenium/server"), chromeOptions.ToCapabilities());
