Firefox Work Without Marionette? (Running Python Selenium 3 Against Ff 53) - Geckodriver/Firefox without Marionette: Python Selenium 3 guide

In the world of web automation, Python Selenium has given developers an upper hand in performing automated testing on web applications. However, this is only achievable with proper installation of GeckoDriver and Firefox without Marionette.

GeckoDriver serves as a bridge whereby Python Selenium interacts with the Firefox browser. Without it, automated testing on Firefox browser becomes impossible. The good news is, the installation process is pretty straightforward, and with the right guide, anybody can achieve it.

Furthermore, for optimal results, it’s recommended to avoid using Firefox with the Marionette driver. This is because Firefox with Marionette has restrictions that limit its functionality, leading to failure during runtime. Instead, using GeckoDriver and Firefox without Marionette ensures a smoother, reliable, and efficient automated testing process.

This Python Selenium 3 guide with GeckoDriver and Firefox without Marionette provides everything you need to get started with web automation that provides consistent and reliable results. From installation procedures to application in the real world, this guide offers step-by-step instructions. By the end of it, you’ll be equipped with the necessary knowledge to launch your automated testing process in no time.

Invite readers to check out the article to get all the juicy details about setting up GeckoDriver and Firefox without Marionette with this Python Selenium 3 guide today.

Selenium WebDriver is an open-source browser automation framework that allows the development of web tests. It supports multiple programming languages including Python, Ruby, Java, and C#. Selenium mainly uses drivers to interact with different browsers. In this blog article, we will compare Geckodriver/Firefox without Marionette.


Geckodriver is a proxy server that allows communication between the WebDriver and the Firefox browser. It is the official WebDriver implementation that is required for Firefox version 47 and above. Geckodriver is written in Rust and is faster than the older Firefox driver. It makes use of the W3C WebDriver protocol and has better error messages making it easier to debug.

Advantages of Geckodriver

  • Faster than the previous Firefox driver
  • Better error messages
  • Supports the W3C WebDriver protocol

Firefox without Marionette

Marionette was introduced in Firefox version 48 as a new remote protocol that provides a more reliable and efficient way of interacting with the browser. However, it also adds additional overhead compared to Geckodriver. Firefox without Marionette is simply the previous implementation of FirefoxDriver that uses the legacy Firefox remote protocol to interact with the browser.

Advantages of Firefox without Marionette

  • No need for additional dependencies
  • No added overhead compared to Geckodriver
  • Works well with older versions of Firefox

Comparison Table

Feature Geckodriver/Firefox with Marionette Firefox without Marionette
Efficiency Efficient but slower than Geckodriver Efficient but prone to crashes
Dependency Requires Geckodriver No additional dependencies required
Debugging Easier to debug with more detailed error messages May be harder to debug due to limited error messages


In conclusion, both Geckodriver/Firefox with Marionette and Firefox without Marionette have their own advantages and disadvantages. If you are running Firefox version 47 and above, then go for Geckodriver as it is the official WebDriver implementation that is supported by Mozilla. For those who are using older versions of Firefox or do not want to depend on additional drivers, then Firefox without Marionette would be a good choice. In terms of efficiency, Geckodriver is relatively faster while Firefox without Marionette is efficient but may be prone to crashes. Lastly, it is easier to debug with Geckodriver thanks to more detailed error messages which can save time during troubleshooting.

Here are some common questions people ask about using Geckodriver/Firefox without Marionette in a Python Selenium 3 guide:

  1. What is Geckodriver?

    Geckodriver is a proxy for using W3C WebDriver-compatible clients to interact with Gecko-based browsers like Firefox.

  2. What is Marionette?

    Marionette is the remote protocol that Firefox uses to communicate with GeckoDriver. It is built into newer versions of Firefox and is not required when using Geckodriver.

  3. Why would I want to use Geckodriver without Marionette in Python Selenium 3?

    Some users may prefer to use Geckodriver without Marionette because it can provide greater control and flexibility when interacting with Firefox. Additionally, Marionette is not available in all versions of Firefox.

  4. How do I use Geckodriver without Marionette in Python Selenium 3?

    To use Geckodriver without Marionette in Python Selenium 3, you need to set the marionette option to False when creating the Firefox instance:

    from selenium import webdriver
    options = webdriver.FirefoxOptions()
    options.set_capability(marionette, False)
    driver = webdriver.Firefox(options=options)
