Proxy is not loading

[M-Zubair10]

I am using seleniumbase for a long time, same script, nothing changed but it is no longer loading proxy.

Tried loading extension or by using seleniumbase parameter, none of them work. What work is by going to chrome://extension and loading proxy manually

from seleniumbase import Driver  # noqa
self.driver = Driver(headless2=self._headless2, headless=self._headless, uc=True,
        user_data_dir=self._user_data_dir,
        page_load_strategy=self._options.page_load_strategy,
        window_size=f"{self._w},{self._h}", window_position=f"{self._x},{self._y}",
        extension_dir=str(self._proxy.extension_dir) if self._proxy else None
)```

Not working in vanilla selenium and undetected_chromedriver too.

Make sure you’re using the latest version of SeleniumBase. Chrome 137 had major changes that affected extensions, (which affects proxy authentication), but that was already patched in SeleniumBase.

Once you've upgraded, you can set the proxy arg: "user:pass@server:port".
