SeleniumBase and Selenium are no longer loading the extensions.

[AllanFnds]

Previously I used the following codes:

options.add_argument('--load-extension=')
options.add_argument('--disable-features=DisableLoadExtensionCommandLineSwitch')

And this worked, but now it doesn't work anymore in Selenium, not even using SeleniumBase.
Existis any solutions?

[mdmintz]

I created this ticket for overseeing the issue: #4053. It's related to changes in Chrome 142.

@mdmintz - seleniuimbase stopped authenticating proxy credentials for me, is this related to this?

[mdmintz]

Yes, related to a Chrome 142 change. I'm working on the fix. Expect a new release soon.

[alexander01202]

Still no fix?

[mdmintz]

The proxy auth fix was already rolled out. Now auth happens when activating CDP Mode if you’re using UC Mode. Upgrade to a newer version of SeleniumBase if you experience any issues with proxy auth.

with SB(uc=True,
proxy=proxy,
) as sb:
# url = "https://pixelscan.net/fingerprint-check"
url = "https://demo.fingerprint.com/playground"
timezone = get_timezone(proxy)
print(timezone)
sb.activate_cdp_mode(url,
# tzone=timezone
)
And pixelscan doesn't work either.

[mdmintz]

No issues with Pixelscan and proxy auth: (Bot not detected)

from seleniumbase import SB

with SB(uc=True, test=True, proxy="USER:PASS@IP:PORT") as sb:
    url = "https://demo.fingerprint.com/playground"
    sb.activate_cdp_mode(url)
    sb.sleep(1)
    sb.cdp.highlight('a[href*="browser-bot-detection"]')
    bot_row_selector = 'table:contains("Bot") tr:nth-of-type(3)'
    print(sb.get_text(bot_row_selector))
    sb.assert_text("Bot Not detected", bot_row_selector)
    sb.cdp.highlight(bot_row_selector)
    sb.sleep(2)

from typing import Literal

from seleniumbase import Driver

from seleniumbase.core import proxy_helper

def create_driver(
    browser: Literal["chrome", "firefox"] = "chrome",
    headless: bool = False,
    proxy: bool = False,
    selenium_wire: bool = False,
):
    if proxy:
        proxy_helper.create_proxy_ext(proxy_string="pr.oxylabs.io:7777", proxy_user="user", proxy_pass="password")

    driver = Driver(
        browser=browser,
        headless=headless,
        # uc_cdp=True,
        # uc=True,
        incognito=True,
        ad_block_on=True,
        do_not_track=True,
        # undetectable=True,
        # uc_cdp_events=True,
        use_wire=selenium_wire,
        extension_dir="downloaded_files/proxy",
    )
    driver.maximize_window()
    return driver

When I use the driver like this, the proxy and ad_block works. But if I uncomment any of those parameters (uc_cdp, uc, undetectable, uc_cdp_events) they dont work. Am I doing anything wrong?

[mdmintz]

When using UC Mode, you have to call activate_cdp_mode(url) for proxy auth to take effect now. (This is due to Chrome-142's removal of the --load-extension option and the --disable-features=DisableLoadExtensionCommandLineSwitch workaround.)

Proxy auth is set via CDP now, rather than via extension.

[Lima-e-Silva]

Thanks for the quick reply! Proxy auth is working now.

[Acolyte]

And how do you change proxy via CDP, @mdmintz? Can you provide an example for it?

[mdmintz]

Proxy is set in the beginning, and auth takes effect when activating CDP Mode:

from seleniumbase import SB

with SB(uc=True, proxy="USER:PASS@IP:PORT") as sb:
    sb.activate_cdp_mode(url)
