Have the same issue. Started with Puppeteer 10.

I have same problem.

I am trying to use local tor proxy with puppeteer, but for some reason it is not using it:

const puppeteer = require('puppeteer');

async function getPic(arg){
    console.log(arg);
    const browser = await puppeteer.launch({
    args: [
      '--proxy-server=socks5h://127.0.0.1:9050',
    ],
    });
    var gh = 0;
    while(gh < 1000){
      const context = await browser.createIncognitoBrowserContext();

      const page = await context.newPage();

    await page.goto('http://ipinfo.io/',{waitUntil: 'networkidle2'});
    await page.screenshot({path: 'screenshot.png'});

    console.log("done for" + gh);
    gh++;
  }
    await browser.close();
}

getPic(process.argv[2]);

As a result I still see my original IP on the result screenshot. Proxy is working correctly, I checked with curl.

Did somebody check if this is a Chrome or a Puppeteer issue? Did Chrome perhaps change the parameter?

💥💥 Tor PROXY doesn't work when using incognito mode 💥💥

Found out that my local ISP blocked the proxy. When I turned on an vpn the proxy worked perfectly.

Please note that the last working version of puppeteer is 10.2, any above that the incognito proxy function is still broken.
