Firefox

This Unblocking Browser provides a Firefox-based browser with advanced stealth capabilities. It's specifically designed to evade bot detection through built-in modifications and automatic residential proxy integration.

Please note that the latest supported Playwright version for the Firefox endpoint is 1.51.x (e.g., version 1.52.x is not supported).

Key features

• Superior stealth with built-in anti-detection modifications

• Firefox-based implementation for improved uniqueness

• Any proxy country selection

• Advanced fingerprint management

Connection details

Connect to UBS using the following WebSocket endpoint:

wss://ubs.oxylabs.io

Important considerations

• Requires explicit use of the firefox implementation in automation libraries

• May require minor adjustments compared to Chrome-based solutions

Basic usage

Python

from playwright.sync_api import sync_playwright

username = "your-username"
password = "your-password"
endpoint = "ubs.oxylabs.io"
browser_url = f"wss://{username}:{password}@{endpoint}"

with sync_playwright() as p:
    browser = p.firefox.connect(browser_url, timeout=60000)
    page = browser.new_page()
    page.goto('https://example.com')
    browser.close()

JavaScript

United States proxy infrastructure

Users, who mainly operate in the US, can connect directly to US-based infrastructure via the special entry point. This ensures faster loading time and better browsing efficiency. To establish connection, select the following:

wss://ubs-us.oxylabs.io

Code examples:

Python

from playwright.sync_api import sync_playwright

username = "your-username"
password = "your-password"
endpoint = "ubs-us.oxylabs.io"
browser_url = f"wss://{username}:{password}@{endpoint}"

with sync_playwright() as p:
    browser = p.firefox.connect(browser_url, timeout=60000)
    page = browser.new_page()
    page.goto('https://example.com')
    browser.close()

JavaScript

Note: this solution primarily shortens the response time for the US-based users, and should not be confused with proxy geo-location selection. More on that in the following section.

Country selection

You can specify a country for your browser session by adding the ?p_cc parameter to your connection URL. Here are examples:

Python

from playwright.sync_api import sync_playwright

username = "your-username"
password = "your-password"
endpoint = "ubs.oxylabs.io"
country = "US"  # Replace with desired country code
browser_url = f"wss://{username}:{password}@{endpoint}?p_cc={country}"

with sync_playwright() as p:
    browser = p.firefox.connect(browser_url, timeout=60000)
    page = browser.new_page()
    page.goto('https://example.com')
    browser.close()

JavaScript

If no country is specified, the system will automatically assign one based on availability.
