In this section, we will see how we can download, setup, and use GeckoDriver on the Windows operating system. In the next section, we will see how we can set up GeckoDriver in our system. We can resolve the above exception by using GeckoDriver in place of the regular FirefoxDriver. Note: If you have GeckoDriver set up in your system already, you will not get any error like this. On running the above code, you will get IllegalStateException, as shown below: Let us see what happens if we do not use GeckoDriver with Selenium 3 or latest through below example- package gecko Hence, we need GeckoDriver to instantiate an object and launch Firefox. So, we have to use Selenium 3, which has the MarionetteDriver. Marionette driver is an automation driver for Mozilla, which can directly control the UI or internal JavaScript of a Gecko platform like Firefox. As a result, it is challenging to use Selenium 2 with the latest Firefox versions. But after Firefox v47.0+, we need to use a proxy to interact with the browser.Īlso, with Firefox 47.0+, it is not possible to have any third party driver interact directly with the browser. Just a simple line of code, as shown above, would open the Firefox browser. Moreover, the WebDriver directly implements the FirefoxDriver, due to which there was no need to use any executable to launch Firefox. To understand it more, refer below diagram:īefore Marionette became a part of Firefox, the default browser of WebDriver was Firefox, and it had its inbuilt driver to launch the Firefox browser.

Additionally, this could be done directly by using the below line of code, and you could instantiate Firefox driver using the WebDriver reference like below: WebDriver driver = new FirefoxDriver() With earlier versions of Selenium (like version 2.53 & below ), launching the Firefox browser was straightforward. Now that we know the working of the firefox driver let us understand why we need it to execute our Selenium tests. Hence, the execution happens inside the browser. The client or the local system sends a request, which is the WebDriver call to the GeckoDriver. The GeckoDriver converts these request( s) into Marionette Protocol and transfers to Marionette Driver. Now, the server sends back the response to the client via the GeckoDriver. Additionally, to understand more about how it interacts, refer to the diagram below: It works as a proxy between the local and remote end to translate calls into Marionette automation protocol. Just like the other drivers( e.g., ChromeDriver), a local server is started by this executable, which runs your selenium tests. The WebDriver connects with the firefox browser using the GeckoDriver. Moreover, it is an executable file that the system paths for your test required. In simple words, GeckoDriver or Firefox driver links our Selenium tests with the Mozilla Firefox browser. Therefore, sometimes people often refer to it as Firefox driver when they mean it is the GeckoDriver. In other words, GeckoDriver is a proxy that interacts between W3C WebDriver-compatible clients and Gecko-based browsers like Firefox. GeckoDriver is the link between Selenium tests and the Firefox browser. Additionally, we can use it on Windows, macOS, Linux, Unix & BSD operating systems. The GeckoDriver is in C++ and JavaScript, as well in Rust since 2016. Different applications developed by Mozilla Foundation or Mozilla Corporation use it. Gecko is a web browser engine that has been developed by Mozilla. Let us first understand Gecko before understanding the GeckoDriver.

We will primarily focus on the below points in this article: Subsequently, in this article, we'll learn everything about Selenium GeckoDriver and see how we can use it in our selenium scripts. Lately, with the introduction of Selenium 3 and 4, Gecko Driver usage has become a necessity.

While the user base is continuously increasing, new features continually added, and over time new version( s) of Selenium is being launched. Selenium is one of the most used tools for Web automation in the IT industry these days.
