WebExtension that spoofs some webGl data and few other features unique to headless browsers, so they'll be harder to detect/fingerprint
- sets navigator.webdriver to false
- sets navigator.languages to random value
- emulates some webGL 1.0 functions/extensions (for best results use with Canvas Defender)
- returns random height/width from broken images
- supports hairline (css modernizr)
- Zip files from src zip -rj extension.zip src/*
- Change archive extension to *.xpi mv extension.zip extension.xpi
- Load into webdriver
from selenium import webdriver
options = webdriver.FirefoxOptions()
options.add_argument('--headless')
driver = webdriver.Firefox(firefox_options=options)
extension_path = 'path_to_extension_in_xpi_format'
# True flag enables installation of unsigned extensions
driver.install_addon(extension_path, True)
# Check what data is spoofed
driver.get('https://browserleaks.com/webgl')
driver.quit()Tip: for best results use with extension like CanvasBlocker
- implement more webGL functions/extensions
- find a way to return fake webGl hash for generated canva
