Does browser support WebDriver or does WebDriver support browser - selenium

Is it the browser job to support WebDriver or is it WebDriver job to support each browser?
I mean if there is a new release of Chrome does this mean that WebDriver works right away because the support is included in the new Chrome release?
Or is WebDriver support added later by the developers of WebDriver?

To run selenium webdriver in Chrome browser, we need to take the help of ChromeDriver which is a separate executable that selenium webdriver uses to control chrome. ChromeDriver is supported by the Chromium team, ChromeDriver is a standalone server which implements WebDriver's wire protocol for Chromium.

Yes, Webdriver made changes later that's the reason new jars of selenium launches so rapidly.
Hope it will help you :)

Using webdriver plugin in jmeter

Iam trying to use webdriver plugin to automate an application in jmeter. Can anyone help me to do scripting in selenium by using webdriver plugin. Thanks in advance.
It depends on the browser and programming language you're using.
Currently Chrome is the most popular browser and JavaScript is the default language for the WebDriver Sampler so:
Download chromedriver (make sure that the version you download matches your Chrome browser version)
Add Chrome Driver Config and specify the path to the chromedriver in the "Chrome" tab:
Add WebDriver Sampler and implement the code for your test scenario. WDS.browser will stand for the ChromeDriver instance so you will be able to: use
WDS.browser.get('some url') - open a page
var element = WDS.browser.findElement(org.openqa.selenium.By.id('some id')) - locate a WebElement
element.click() - click the element found in the previous step
etc.

ITest with different browser version via webdriver

I'm starting to write a test scenario with selenium web driver and test it via different firefox and IE versions. So, I downloaded GeckoDriver and selenium webdriver itself.
The question is, what version of selenium webdriver, firefoxdriver (gecko driver) and IE driver in order to test my scenario in different browser versions?
for example firefox since version 35 and IE since version 7.
Is there any references to see which firefox version works with which gecko driver and webdriver versions?
this will helps you

better way is to check change log in http://www.seleniumhq.org/download/
exp: for gecko https://github.com/mozilla/geckodriver/blob/release/CHANGES.md
and webdriver https://raw.githubusercontent.com/SeleniumHQ/selenium/master/java/CHANGELOG

How to run chrome driver in headless mode or in background

I've been using chrome driver (with selenium webdriver), so far it never caused any issue, now for some requirement i want to run test cases in background. How can I do this?
Currently Chrome 59 supports headless mode.
You just need to use those chromeOptions to use headless chrome in selenium.
chromeOptions.addArguments("--headless");
chromeOptions.addArguments("--disable-gpu");
You can refer below link for more details:
https://www.automation99.com/2017/07/how-to-use-chrome-headless-using.html
According to this post Any way to start Google Chrome in headless mode?, a new flag --headless is available in Chromium but Selenium is still to catch up as far as my limited googling skills tell me.
In the mean time you can explore HTMLUnitDriver for headless testing.
WebDriver driver = new HtmlUnitDriver((BrowserVersion.CHROME), true);

Suitable Chrome driver to use with selenium tests

I was wandering since there is many chrome drivers available on the nuGet Packages Manager, which one is fitting the best with Selenium tests, does it make any difference at all?
WebDriver ChromeDriver
WebDriverChromeDriver
Selenium.WebDriver.ChromeDriver
etc...
I'm using for my >30K lines of code (and 6 different web-sites) UI test project the
WebDriver ChromeDriver
with version 26.14.313457.1, it's a separate executable that WebDriver uses to control the Chrome browser. Again it requires Chromium/Google Chrome to be installed.

Why do we need IEDriver and ChromeDriver but no Firefox Driver?

I have small doubt.
Why do we need IEdriver and Chrome Driver running selenium scrits in IE and Chrome but we do not need a firefox driver to run the script?
Is there any reason for the same?
This is because of the Native Browser approach used in WebDriver.
Each and every browser uses different JS Engine.
All drivers [Chrome Driver, IE driver, etc.,] are built based on the special JS Engine used by each browser.
Selenium offers inbuilt driver for Firefox but not for other browsers. [Not sure it may happen in future, since TestNG and JUnit library files are a part of Selenium-standalone-server right now]
Straight from a google search for FirefoxDriver, the official documentation states:
Firefox driver is included in the selenium-server-stanalone.jar available in the downloads. The driver comes in the form of an xpi (firefox extension) which is added to the firefox profile when you start a new instance of FirefoxDriver.
External drivers are the preferred process by the Selenium developers. They allow the driver versioning to be tied more closely to the browser than to Selenium, and they can be supported by the browser authors (e.g., ChromeDriver, OperaDriver). There is a long-standing plan to replace FirefoxDriver with a Mozilla-supported driver based on Mozilla's "Marionette" architecture.
Firefox driver is already included in the selenium-server-standalone.jar package.
