navigator.webdriver still can be detected

const puppeteer = require('puppeteer-extra')
const StealthPlugin = require('puppeteer-extra-plugin-stealth')
puppeteer.use(StealthPlugin())

puppeteer.launch({ headless: true }).then(async browser => {
    const page = await browser.newPage()
    page.on('console', msg => console.log(msg.text()))
    await page.goto('https://bot.sannysoft.com')
    await page.evaluate(async () => {
        console.log('webdriver' in navigator ? 'detected': 'not detected')
        console.log(navigator.webdriver === undefined ? 'not detected': 'detected')
        // but!
        console.log(Object.getOwnPropertyDescriptor(navigator.__proto__, 'webdriver') === undefined ? 'not detected': 'detected once')
        for (let prop in navigator) {
            if (prop === 'webdriver') {
                console.log('detected twice')
            }
        }
    });

    await browser.close()
})

const newProto = navigator.__proto__;
delete newProto.webdriver;
navigator.__proto__ = newProto

was more correct way to remove webdriver from navigator.

There is no way __proto__ will get deleted from Chrome anytime soon, it will break too many sites. But in case it will, this works as well:

delete Object.getPrototypeOf(navigator).webdriver;

very good！ delete navigator.__proto__.webdriver;
