A headless browser is a web browser without a user interface, it means the browser is running in the background (invisbile). This is great if you want to start a web browser to do tasks, but you don’t want or need to see it.
You can use any Web Browser like Firefox or Chrome in a headless mode. To do so, first open up the Web Browser using the Web Driver and then set it to headless mode. In any case, the web driver needs to be installed.

Selenium is a web automation framework that can be used to automate website testing. Because Selenium starts a webbrowser, it can do any task you would normally do on the web. If you are new to selenium and browser automation, I recommend the course below. Download selenium-firefox-driver-2.4.0.jar. Selenium-firefox/selenium-firefox-driver-2.4.0.jar.zip( 1,123 k) The download jar file contains the following class files. Gecko Driver serves as a link between your tests in Selenium and the Firefox browser. It acts as a proxy between W3C WebDriver-compatible clients (Eclipse, Netbeans, etc.) to interact with Gecko-based browser (Mozilla Firefox). Marionette (the next generation of FirefoxDriver) is.

selenium firefox headless
Before you start, make sure the Web Browser, the Web Driver and the selenium module are all installed and working.
The code below starts Firefox, but in headless mode. It can do anything Firefox can, but it wont be visible on the screen. The screenshot below outputs the html code of the web page, but that’s optional.
It’s set as headless browser here, where FirefoxOptions() is used to make it headless.
After loading the headless web browser, you can proceed to using it as you would normally do with selenium. The only difference is that it’s not visible to the user.
If you are new to selenium, then I highly recommend this book.
Firefox can be controlled by Python. To do this you need the selenium module and a web driver. The Python code starts the web browser and then completely controls it.
The code can then do anything you can do with a web browser, like opening a page, sending key presses or button clicks.

Firefox
Selenium Firefox Example
To make Firefox work with Python selenium, you need to install the geckodriver. The geckodriver driver will start the real firefox browser and supports Javascript.
From python you can load the Firefox browser with one line of code:
Take a look at the selenium firefox code. First import the webdriver, then make it start firefox.
Open a webage with the get page and optionally send keypresses.
What is GeckoDriver?
Selenium Firefoxdriver
The web browser Mozilla Firefox uses an engine named the Gecko browser engine. The engine was created by the Mozilla foundation.
Because it’s an engine, it can be used in other web browsers (just like how engines can be used in other cars). Every browser has their own engine, but sometimes they use the same engine to display web pages.
GeckoDriver is what is between Selenium and the FireFox browser. It lets you control the Firefox web browser from Python code. All web browser commands go through the GeckoDriver, the GeckoDriver in turn makes your browser do what you want.
Selenium Firefox Path
The GeckoDriver is a different executable on every operating system. On Windows it is GeckoDriver.exe, but on Mac there are no .exe files, so it’s named differently.
The GeckoDriver must match the Firefox version, otherwise you can get incompatibility issues or have the issue that it simply doesn’t work.
Headless Firefox
There are several parameters you can specify, one of them is headless. If you want to make Firefox headless (invisible), you add that as parameter in FirefoxOptions.
