Now that we’ve explored the advantages let’s dive into the practical steps to set up headless Firefox Selenium with a smart proxy for scraping Walmart product pages. This process involves several key components, and we’ll guide you through each one.
To set up headless Firefox Selenium with a smart proxy, you need to ensure that you have the necessary software and drivers installed on your system. Here’s a detailed guide on how to do that:
Install Mozilla Firefox:
Mozilla Firefox is the web browser that Selenium will use for web automation. You can download it from the official Firefox website. Ensure you download the latest stable version compatible with your operating system.
Python is a programming language mostly used to write Selenium scripts. Most operating systems come with Python pre-installed. However, it’s essential to have Python installed on your system.
To check if Python is already installed, open your terminal or command prompt and type:
If Python is not installed, you can download it from the official Python website. Download the latest stable version for your operating system.
Download Firefox Geckodriver:
Geckodriver is a crucial component for Selenium to interact with Firefox. It acts as a bridge between Selenium and the Firefox browser. To download Geckodriver, follow these steps:
Visit the Geckodriver releases page on GitHub.
Scroll down to the section labeled “Assets.”
Under the assets, you’ll find the latest version of Geckodriver for your operating system (e.g.
geckodriver-vX.Y.Z-win64.zipfor Windows or
geckodriver-vX.Y.Z-linux64.tar.gzfor Linux). Download the appropriate version.
Once downloaded, extract the contents of the ZIP or TAR.GZ file to a directory on your computer. Note down the path to this directory, as you’ll need it in your Python script.
Selenium is a powerful tool for automating web interactions, and it’s the core of our web scraping setup. Install Selenium using Python’s package manager, pip, with the following command:
pip install selenium
Additionally, we’ll use a library called Random User Agent to generate random user-agent strings for oupip install seleniumr browser. Install it using pip as well:
pip install random-user-agent
Crawlbase offers a range of web scraping solutions, including smart proxies compatible with Selenium. Open your web browser and navigate to the Crawlbase website.
If you’re a new user, you’ll need to create an account on Crawlbase. Click the “Sign Up” or “Register” button to provide the required information. You can find your Smart Proxy URL here once you’re logged in. Crawlbase Proxy URL will look like this.
Crawlbase offers various proxy plans based on your web scraping needs. Check out more about Crawlbase proxy plans. These plans may vary in terms of the number of proxies available, their locations, and other features. For a good start, Crawlbase provides a Free trial with limited features for one month. Review the available plans and select the one that best suits your requirements by reading Crawlbase Smart Proxy documentation.
Now, let’s configure Selenium to use the smart proxy. To use a Crawlbase smart proxy with Selenium Firefox driver in a Python script, create a Python script with your desired name and add the following code to it:
Step 1: Import Necessary Libraries
Here, we import the required Python libraries and modules. These include Selenium for web automation, random_user_agent for generating random user agents, and others for configuring the Firefox browser.
Step 2: Generate a Random User Agent
user_agent_rotator = UserAgent(
Here, we create a random user agent for the Firefox browser. User agents help mimic different web browsers and platforms, making your scraping activities appear more like regular user behavior.
Step 3: Configure Firefox Options
firefox_options = Options()
In this part, we set various options for the Firefox browser. For example, we make it run in headless mode (without a visible GUI), set window size, disable GPU usage, and apply the random user agent generated earlier.
Step 4: Define Your Smart Proxy URL
proxy_host = "http://[email protected]"
In this section, you should replace YourAccessToken with the token you obtained from the Crawlbase. This proxy_host and proxy_port will be used to route your web requests through the smart proxy.
Step 5: Set Up the Smart Proxy for Firefox
This section is setting up a proxy server for Firefox. The first line sets the proxy type to 1, which is “manual proxy configuration.” The next eight lines set the proxy server host and port for HTTP, HTTPS (SSL), FTP, and SOCKS connections. The last line disables the cache for HTTP connections.
Step 6: Specify the Firefox Geckodriver Path
fireFoxDriverPath = os.path.join(os.getcwd(), 'Drivers', 'geckodriver')
This line specifies the path to the Firefox Geckodriver executable. Make sure to provide the correct path to the Geckodriver file on your system.
Step 7: Create a Firefox Driver with Configured Options
firefox_service = Service(fireFoxDriverPath)
This line specifies the path to the Firefox Geckodriver executable. Ensure you provide the correct path to the Geckodriver file on your system.
To check if the proxy is functioning correctly and your IP is being routed through it, you can use a simple example. We’ll make a request to the
http://httpbin.org/ip URL and display the proxy IP returned in the HTML body. Add the following code at end of your script you created in previous step.
# Access the http://httpbin.org/ip URL to see if the IP has changed
In this code, we use Selenium’s
driver.get() method to navigate to the
http://httpbin.org/ip URL, where we intend to gather information about the IP address.
Within a try block, we employ Selenium’s WebDriverWait in conjunction with
EC.presence_of_element_located. This combination allows us to await the presence of an HTML element tagged as “body”. To ensure that we don’t wait to long, we set a maximum waiting time in seconds for our condition to meet in WebDriverWait, defined as
time_to_wait. This step is vital to ensure that the webpage has indeed loaded in its entirety.
Once the webpage is fully loaded, we extract its HTML source using the
drver.page_source method. After getting the HTML, we are locating and retrieving the IP address from the HTML body. We achieve this by searching for the “body” tag and extracting its text content.
By following these steps, you can start Firefox in headless mode, access a URL to check the IP, and verify that your requests are indeed being routed through the smart proxy.
This section will delve into a practical example of using headless Firefox Selenium with a smart proxy to scrape valuable data from a Walmart product page. We’ll provide you with code and introduce a valuable function to streamline the scraping process.
To successfully scrape data from a Walmart product page, it’s crucial to comprehend the underlying structure of the page’s HTML. Walmart’s product pages are well-organized and contain valuable information such as the product name, price, description, reviews, and more.
To scrape the important information from Walmart product page, you can inspect the Walmart page HTML and find a unique selector to the elements where desired information is present. Let’s break down the essential elements and how to identify them for scraping:
- Product Title: The product title, which is often the most prominent element on the page, is typically located within an h1 HTML element with the id
main-title. We can use the XPath expression
'//h1[@id="main-title"]'to precisely locate this title.
- Product Price: The product price is another critical piece of information. It can usually be found within a span HTML element containing the data attribute with name
testidand value as
price-wrap. Inside this element, the price will be inside a span with attribute
price. To locate it, we use the XPath expression
- Product Description: While the product description is not covered in this example, it can be located in various ways depending on its placement in the HTML structure. You can inspect the page’s source code to identify the appropriate HTML element and XPath for scraping the description.
- Customer Reviews: Similarly, customer reviews can be located using XPath expressions that target the HTML elements containing review data, typically found under a section titled “Customer Reviews.”
Note: The HTML elements referenced above were current when writing this blog. Please be aware that these elements may undergo changes or updates in the future.
Understanding these key elements and their respective XPath expressions is fundamental to web scraping. By analyzing the HTML structure of Walmart product pages, you’ll be well-equipped to extract specific data points for your scraping needs.

This patient approach ensures the accuracy and reliability of the data retrieval process.
The script incorporates essential configurations to enhance its versatility. It dynamically generates random user agents, emulating various web browsers and operating systems. This dynamic user-agent rotation helps mask the scraping activity, reducing the risk of detection by the target website. Furthermore, the script optimizes Firefox settings, rendering the browser headless (without a visible interface), configuring window dimensions, and disabling GPU acceleration to improve performance. It also demonstrates leveraging a proxy server, an invaluable feature in scenarios necessitating IP rotation or anonymity.
To bolster the script’s robustness, it includes a built-in retry mechanism. This mechanism gracefully handles timeouts or exceptions by allowing users to specify the maximum number of retry attempts and the duration of pauses between retries.
In the main execution block, the script initializes crucial components such as user agents, Firefox options, and proxy settings. It also specifies the URL of the Walmart product page to be scraped. The
scrape_walmart_product_page function is then invoked with the chosen URL, initiating the scraping process.
Product Title: Ozark Trail Basic Mesh Chair, Blue, Adult
