Firefox

Unblocking Browser supports two specialized browser environments, one of which is Firefox. Learn more on how to start using it.

A Firefox-based browser environment with advanced stealth capabilities. It's specifically designed to evade bot detection through built-in modifications and automatic residential proxy integration.

The Firefox endpoint supports two Playwright versions: 1.51 and 1.56. Other versions are not supported. You can specify the Playwright version via the o_pw parameter, for example:

wss://USER:[email protected]?o_pw=1.56

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

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()

const { firefox } = require('playwright');

(async () => {
    const username = 'your-username';
    const password = 'your-password';
    const endpoint = 'ubs.oxylabs.io';
    const browserUrl = `wss://${username}:${password}@${endpoint}`;

    const browser = await firefox.connect(browserUrl, { timeout: 60000 });
    const page = await browser.newPage();
    await page.goto('https://example.com');
    await browser.close();
})();

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:

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()

const { firefox } = require('playwright');

(async () => {
    const username = 'your-username';
    const password = 'your-password';
    const endpoint = 'ubs-us.oxylabs.io';
    const browserUrl = `wss://${username}:${password}@${endpoint}`;

    const browser = await firefox.connect(browserUrl, { timeout: 60000 });
    const page = await browser.newPage();
    await page.goto('https://example.com');
    await browser.close();
})();

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:

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()

const { firefox } = require('playwright');

(async () => {
    const username = 'your-username';
    const password = 'your-password';
    const endpoint = 'ubs.oxylabs.io';
    const country = 'US';  // Replace with desired country code
    const browserUrl = `wss://${username}:${password}@${endpoint}?p_cc=${country}`;

    const browser = await firefox.connect(browserUrl, { timeout: 60000 });
    const page = await browser.newPage();
    await page.goto('https://example.com');
    await browser.close();
})();

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