How to increase fingerprint emulation

[AlexPaiva]

What other means of anti fingerprint can I implement that are randomized and emulated randomly when using UC that will help in making the fingerprint completely random when having a high number of threads on the same site but want each thread to look completely different from the first?

You could try using multiple proxy servers to vary things up.
You'll have to supply your own proxy config for that to work.

from parameterized import parameterized
from seleniumbase import BaseCase
BaseCase.main(__name__, __file__, "-n3")

class ProxyTests(BaseCase):
    @parameterized.expand(
        [
            ["host1:port1"],
            ["host2:port2"],
            ["host3:port3"],
        ]
    )
    def test_multiple_proxies(self, proxy_string):
        self.get_new_driver(
            undetectable=True, proxy=proxy_string, multi_proxy=True
        )
        self.driver.get("https://browserleaks.com/webrtc")
        self.sleep(30)

Confused, I meant how to emulate the fingerprint not related to location such as canvas etc

See #2248 (comment)

Even before UC Mode existed, there was an integration with selenium-stealth (#942 (comment)), which lets you "change" (fake) various properties:

You can integrate it directly into the custom setUp() method of your tests like this after you pip install it:

from seleniumbase import BaseCase
from selenium_stealth import stealth

class BaseTestCase(BaseCase):
    def setUp(self):
        super().setUp()
        stealth(self.driver,
            languages=["en-US", "en"],
            vendor="Google Inc.",
            platform="Win32",
            webgl_vendor="Intel Inc.",
            renderer="Intel Iris OpenGL Engine",
            fix_hairline=True,
        )

Then have your test classes inherit BaseTestCase instead of BaseCase. (See SeleniumBase/help_docs/syntax_formats.md#sb_sf_02)

There's general information on StackOverflow about that here: https://stackoverflow.com/q/70265306/7058266

Additionally, you could use driver.execute_cdp_cmd() to make internal modifications to your Chrome settings.
You would need to be familiar with CDP internals: https://chromedevtools.github.io/devtools-protocol/tot/Network/.
For example, here's a SeleniumBase script that changes your GeoLocation: SeleniumBase/examples/test_geolocation.py

Oh wow didn't know you had ss integrated, how can I call it from a raw driver?

Any ideas on adding a randomizer for ss of some kind? Like calling ss completely randomized?

[mdmintz]

Wrap your driver with stealth:

from seleniumbase import Driver
from selenium_stealth import stealth

driver = Driver(uc=True)
stealth(driver,
    languages=["en-US", "en"],
    vendor="Google Inc.",
    platform="Win32",
    webgl_vendor="Intel Inc.",
    renderer="Intel Iris OpenGL Engine",
    fix_hairline=True,
)
driver.get("https://browserleaks.com/webrtc")
driver.sleep(10)
driver.quit()

Check with https://github.com/diprajpatra/selenium-stealth for randomization techniques.
That's a separate repo that SeleniumBase integrations with.
