Can you please tell me why it driver is stack on opening or refresging page after setting cookies? I tried pure cdp mode, but i have the same result. Sometimes it opens page for like 10 minutes. Is this code or browser issue?

Calling WebDriver methods from CDP Mode will either remove your stealth or not work at all.

Since sb.driver.add_cookie() can only work on a matching domain, it means you already opened a URL to get there. Calling sb.open() from UC Mode automatically activates CDP Mode now. Using sb.driver.get(URL) instead will keep you in plain UC Mode.

Also why is that website detects pure cdp mode, but not uc mode in docker container?

Somehow website detects me even before i add cookie when i first open website via pure cdp sb = sb_cdp.Chrome(ad_block = True, incognito=True, lang="ru-RU", sandbox=False, proxy=proxy) logging.info("Chrome instance created") sb.get("https://www.ozon.ru/my/main") logging.info("Page loaded") it gets captcha. Are there any stealth parameters?

Could be related to your proxy, or the environment you're running in. (Eg. Docker is detectable.)

What is the stealthiest way to open website, add cookies, refresh page and get new cookies?
