Proxy with auth triggers dialog popup

[lambdina]

Hi,
trying to enable a proxy with authentication. Proxy string is "username:password@ip:port", but it still triggers a dialog popup, which is a system level popup, so not possible to interact with it with Javascript.
Since you discourage to use selenium wire or other Header injection techniques, what should I do ?

Chrome version is chrome=135.0.7049.42

Here is the code :

            browser = Driver(
                locale='fr',
                uc=True,
                user_data_dir=path_to_li_cookies,
                headless2=True,
                proxy="username:password@ip:port",
                agent=UserAgent(browsers=['Chrome', 'Edge', 'Firefox']).random,
                block_images=True,
                size=f'{random.randint(800, 1921)}, {random.randint(800, 1081)}'
            )

Thanks

Good to know :
The proxy provider specifies :
Proxies format is IP:Port:Username:Password

And even when setting up the proxy manually on my laptop, I still have the dialog popup with my browser.

I'm not able to reproduce this.

I also see some discrepancies in your code chunk:

• You're setting headless, yet you somehow have a screenshot.
• You're setting user_data_dir to what looks like a cookie dir.
• You're setting the user agent to a possibly incompatible value.

Note that once you set the user_data_dir, you can't change the proxy after that.
The proxy that you used when initiating the user_data_dir must always be used.

with SB(
        headless=False,
        proxy=proxy,
) as driver:
    driver.get("https://httpbin.org/ip")

There's a situation going on now related to extensions / setting a proxy. See #3771 for details.
