Is there a way to clear session data to ensure a clean session is initiated each time?

For IE you would use capabilities like this:
DesiredCapabilities cap = new DesiredCapabilities();
cap.setCapability(InternetExplorerDriver.IE_ENSURE_CLEAN_SESSION, true);
and possibly in combination with
driver.manage().deleteAllCookies();
How could this be achieved using Chrome and ChromeDriver?

While we work with Internet Explorer Driver we use the field IE_ENSURE_CLEAN_SESSION
IE_ENSURE_CLEAN_SESSION
As per the JavaDocs IE_ENSURE_CLEAN_SESSION is the Capability that defines whether to clean or not browser cache before launching Internet Explorer by IEDriverServer and is configured as follows :
DesiredCapabilities cap = new DesiredCapabilities();
cap.setCapability(InternetExplorerDriver.IE_ENSURE_CLEAN_SESSION, true);
Now let us have a look at GeckoDriver which follows the WebDriver Spec.
GeckoDriver / moz:profile / rust_mozprofile
If you have a closer look at the geckodriver logs closely you will observe that each time geckodriver is called a new moz:profile is scopped out and the details of rust_mozprofile occurs in the following line:
Marionette CONFIG Matched capabilities: {"browserName":"firefox","browserVersion":"56.0","platformName":"windows_nt","platformVersion":"6.2","pageLoadStrategy":"normal","acceptInsecureCerts":false,"timeouts":{"implicit":0,"pageLoad":300000,"script":30000},"rotatable":false,"specificationLevel":0,"moz:processID":5848,"moz:profile":"C:\\Users\\AtechM_03\\AppData\\Local\\Temp\\rust_mozprofile.OfFuR9ogm33d","moz:accessibilityChecks":false,"moz:headless":false}
This log clearly indicates that Marionette scoops out a new "moz:profile":"C:\\Users\\AtechM_03\\AppData\\Local\\Temp\\rust_mozprofile.OfFuR9ogm33d" and this configuration is handled by the WebDriver instance i.e. the GeckoDriver.
You can find a more detailed discussion on moz:profile in Is it Firefox or Geckodriver, which creates “rust_mozprofile” directory discussion.
ChromeDriver
ChromeDriver which is following the same WebDriver Spec does abides (will be abiding) by the same suite.
Incase you are using any stored FirefoxProfile or ChromeProfile, WebDriver will pick up the existing profile where the Stored Browser Configurations are picked up for reuse.
driver.manage().deleteAllCookies();
Irespective of New/Existing FirefoxProfile or ChromeProfile if you add the line :
driver.manage().deleteAllCookies();
Only the cookies gets deleted only to be get restored back to support the Active Browser Session

When i run selenium webdriver code Firefox webdriver not starting through given webaddress

When i tried to start on Firefox web driver its not starting its showing firefox default page
WebDriver dr = new FirefoxDriver();
dr.get("https://www.google.co.in/");
dr.manage().window().maximize();
its not starting its showing firefox default page
Below i attach output image screenshot

Firefox is one of the most compatible browsers with selemium, and at the same time, is one of the least compatible.
I say this because if you do not have the correct version of the selenium library to go with the version of firefox you are running, or vice-versa, it will always fail.
I would start by attempting to switch to a different version of Firefox. Selenium version 2.48.0 supports Firefox versions 24-41, so if your firefox version does not fit within that range, it is more than likely the problem.

I faced the same issue. The solution to this problem is to update the selenium version. When the page u mentioned i.e https://www.mozilla.org/en-US/firefox/43.0.4/firstrun/learnmore/ opens on firefox launch go to Options -> Addons -> Extensions. You will be able to see the Error there. I got "Forefox Webdriver could not be loaded and is disabled".
This was on Firefox 43 with selenium 2.44. Updating to selenium 2.51 rectified the issue.

Sorry, I cannot comment yet but I would like to help. I got the similar issue when I used selenium webdriver integrated in my python script. The problem was with credentials (particularly with the SSL protocols while declaring a new webdriver object). The code I used looked as the following:
driver = webdriver.PhantomJS(executable_path = "/opt/local/bin/phantomjs", service_args=['--ignore-ssl-errors=true'])
As you can see I use a key that ignores ssl errors. This solved my issue, so I am not sure what platform you use to write the code but hope you can find the similar call for the object.
I found the way how people handle untrusted certificates here. Particularly, for FireFox:
//It creates firefox profile
FirefoxProfile profile=new FirefoxProfile();
// This will set the true value
profile.setAcceptUntrustedCertificates(true);
// This will open firefox browser using above created profile
WebDriver driver=new FirefoxDriver();
driver.get("pass the url as per your requirement");
Hope it helps you!
Best.

Try this.. This will resolve the issue..
FirefoxProfile fpi = new FirefoxProfile();
fpi.setPreference("browser.startup.homepage_override.mstone", "ignore");
fpi.setPreference("startup.homepage_welcome_url.additional", "about:blank");
wd = new FirefoxDriver(fpi);
wd.get("http://www.google.com");
if you want to over-ride the properties of firefox, then,
1.first to find the list of browser properties, type "about:config" in the address url
2.use, setPreference method to set/assign the values..

Unable to clear Browser cookies and Session Data with Selenium

I have been using Java Selenium WebDriver along with Appium to perform tests on Mobile environment be it Emulator(Genymotion) or Physical devices (Android). I am using chromedriver, which I am using to perform tests on Web App in Chrome browser. I am looping my cases for multiple sets of data but the application requires a full browser Cookie and all Session data to be deleted before each loop starts.
I tried using driver.Manage().Deleteallcookies(), but it did not work out for me. I read in some threads to try creating a new session of the browser before each loop. So I tried driver.quit() but it ends the chromedriver session and ends the test. I also tried driver.close() but got the same results as driver.quit().
Can any one suggest a way to delete the browser cookies and session data in chrome browser??
My Appium version:1.3.4.1
Chromedriver version:2.3
Device/Emulator i am trying to test on : Nexus5/Samsung Note 3 Android:4.4.4/5.0

You can try using the following to ensure a clear session. Note I never tested that myself. My understanding is that selenium by default create a new session unless you specified something different or load a profile.
DesiredCapabilities capabilities = DesiredCapabilities.chrome();
capabilities.setCapability(CapabilityType.ForSeleniumServer.ENSURING_CLEAN_SESSION, true);
ChromeDriver driver = new ChromeDriver(capabilities);

How do I access my existing cookies using Chrome?

I have cookies with Gmail login info, so that chrome automatically opens my Gmail.
I tried the following code, but it didn't work:
System.setProperty("webdriver.chrome.driver","chromedriver\\chromedriver.exe");
DesiredCapabilities capabilities = DesiredCapabilities.chrome();
capabilities.setCapability("chrome.switches", Arrays.asList("C:\\Users\\Owner\\AppData\\Local\\Google\\Chrome\\User Data\\Default"));
//I also tried using: capabilities.setCapability("chrome.switches", Arrays.asList("--user-data-dir = C:\\Users\\Owner\\AppData\\Local\\Google\\Chrome\\User Data\\Default"));
WebDriver driver = new ChromeDriver(capabilities);
driver.get("https://gmail.com");
I checked the directory of C:\\Users\\Owner\\AppData\\Local\\Google\\Chrome\\User Data\\Default it is okay.
What is the problem in here?

There is a Known issues section on the Chrome Driver official wiki page I haven't noticed before:
Known Issues
3 . Cannot specify a custom profile
Now, I don't know whether this is or isn't outdated. I could not find a bug report for this. It's true that you can't specify a custom profile via Capabilities (as of July 2013), as you discovered. But there is a solution...
The Solution
Here's how I managed to make it run:
ChromeOptions opt = new ChromeOptions();
opt.setBinary("E:\\some\\path\\chrome.exe");
opt.addArguments("--user-data-dir=C:\\Users\\Owner\\AppData\\Local\\Google\\Chrome\\User Data");
driver = new ChromeDriver(opt);
Notice the path to the User data directory - it does not have the \\Default part. And in that case, it works just fine for me, opens up the Chrome profile stored with all the cookies and logins.
I have no idea why the Capabilities solution does not work. It might be worthwile to file a bug as I could not find one on topic.

Using Selenium 2 RemoteWebDriver with ChromeDriver

I searched for an answer to my question here and on the web but couldn't find anything that was helpful to me. Hopefully this isn't too dumb of a question.
I'm trying to get Selenium 2 to work using various browsers. I am using a Mac as a hub and a node and a Windows pc as a node. My problem is with Chrome. I want to initiate the Java code on the Mac and have the Selenium tests run on the Windows pc. To get Chrome to run on localhost I have the following code:
System.setProperty("webdriver.chrome.driver", "Users/xxxxx/chromedriver");
WebDriver driver = new ChromeDriver();
driver.get("http://www.google.com");
This opens up Chrome on the hub/node Mac. How do I get it to open up on the Windows PC? Can I pass anything into the ChromeDriver() class?
I've tried using RemoteWebDriver, and have the following:
System.setProperty("webdriver.chrome.driver", "/Users/xxxxx/chromedriver");
DesiredCapabilities cap = DesiredCapabilities.chrome();
WebDriver driver = new RemoteWebDriver(new URL("http://localhost:9515/wd/hub), cap);
driver.get("http://www.google.com");
The code compiles and executes, but Chrome never comes up. I don't get any errors. Note that I'm initiating the RemoteWebDriver on localhost and Chrome still doesn't work. Nothing changes if I change the URL to the IP of the Windows PC. I'm either doing something wrong with the RemoteWebDriver or I need to pass parameters to ChromeDriver. Please help.

Found the answer after a bit more searching. Turns out that the URL of the remotewebdriver needed to be only localhost:9515 without /wd/hub. Also, if running on another machine, make sure to start up chromedriver on that machine and point webdriver.chrome.driver to the location of chromedriver.
