Rod Version: v0.116.2

First of all, thanks for all the work you're putting into the library!

The code to demonstrate your question

1. Clone Rod to your local and cd to the repository:

func main() {	
	path := `D:\2025zhiwenXUEXI\chrome\Chrome-bin\chrome.exe`
	u := launcher.New().
		Set("headless").
		Delete("--headless").
		Set("user-data-dir", "data/").
		Set("lang", "en-US").
		Bin(path).
		Leakless(true).
		Headless(false)

	launch := u.MustLaunch()
	defer u.Cleanup()

	b := rod.New().ControlURL(launch).MustConnect()
	b.MustPage("https://baidu.com")
	b.MustPage("https://bot.sannysoft.com/")

	time.Sleep(100 * time.Second)
}

What you got

I compiled a chromium browser. Now I need to use go-rod to run my own compiled browser,I can run the browser normally using the above code, but when I use https://bot.sannysoft.com/ to check, the fingerprint information is:

User Agent is always displayed: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/114.0.0.0 Safari/537.36

What you expect to see

I hope go-rod will not modify the parameters on my browser. I can use my own browser's parameter settings normally. What should I do?
The normal display should be my own fingerprint information. I can create a new window manually and it works fine. Example picture:

What have you tried to solve the question

I tried using user mode,Then bin my own browser(https://go-rod.github.io/i18n/zh-CN/#/custom-launch?id=user-mode), but it still doesn't work

You need to disable default device.

b := rod.New().ControlURL(launch).MustConnect().NoDefaultDevice()

You need to disable default device.

b := rod.New().ControlURL(launch).MustConnect().NoDefaultDevice()

Thank you very much! Now it is OK and can run normally, but I have a problem now, that is, the proxy cannot be used normally no matter how I try

`localProxyURL := fmt.Sprintf("http://localhost:%d", localPort)
fmt.Println("这个是本地端口号:", localProxyURL)

//初始化浏览器
launch := launcher.New().
	Bin(PATH).Set("--disable-blink-features", "AutomationControlled").Set("no-first-run").Set("disable-default-apps").
	Leakless(true).
	Headless(false).
	Proxy(localProxyURL).
	//Set("proxy-server", localProxyURL).
	//Set("timezone", "Asia/Tokyo").
	//Set("useragent").
	Set("user-agent", "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/131.0.0.0 Safari/537.36").
	//Set("user-data-dir", "data/1").
	Set("lang", "en-US").
	MustLaunch()

browser := rod.New().ControlURL(launch).MustConnect()`

I just tested it and it seems that I can't set the proxy using the official version of Chrome browser
