• Function: Set browser timezone
• Recommendation: Keep consistent with proxy IP location timezone
• Example: --timezone=America/New_York

• Function: Fingerprint generation seed
• Scope: canvas, webgl, audio, speech, DOMRect, fonts and other fingerprints
• Importance: Keeping the same seed ensures consistent browser fingerprint generation

• Function: Specify Chrome browser version
• Notes:
  • Version number is closely tied to browser APIs; arbitrary changes may cause detection risks
  • Auto-adapts TLS fingerprint (limited version support)
  • Only recommended when target website has strict version control
• Recommendation: Use officially released Chrome version numbers

• Function: Fix iframe-related crash issues in Playwright/Puppeteer
• Fixes: Crashes caused by contentWindow.open

• Function: Control browser language and HTTP request headers
• Affects: Speech recognition, localization-related fingerprints
• Recommendation: Keep both consistent

• Function: Set network proxy server
• Format: --proxy-server=[protocol]://[address]:[port]
• Protocol Support:
  • http: HTTP/HTTPS proxy
  • socks4: SOCKS4 proxy
  • socks5: SOCKS5 proxy
• Example:
  • --proxy-server=http://127.0.0.1:8080

• Function: Set network proxy authentication
• Example:
  • --proxy-auth=username:password

• Function: CPU core count (e.g., i7 has 6 cores, corresponds to navigator.hardwareConcurrency)
• Recommendation: Use common CPU core counts (6, 8, 10, 12)

• Function: System version
• Recommendations:
  • macOS: System version, like 15.4.1, 15.5, etc.
  • Windows:

    Windows Version	Build Number	Platform-Version	Status
    Windows 11 (24H2)	26100+	"19.0.0"	Latest/Preview
    Windows 11 (23H2)	22631	"17.0.0"	Mainstream Recommended
    Windows 11 (22H2)	22621	"15.0.0"	Stable
    Windows 11 (21H2)	22000	"13.0.0"	Initial
    Windows 10 (22H2)	19045	"10.0.0"	Win10 Most Common
    Windows 10 (21H2)	19044	"10.0.0"	Stable
    Windows 8.1	9600	"6.3.0"	Outdated
    Windows 8	9200	"6.2.0"	Outdated
    Windows 7	7601	"6.1.0"	Outdated

• Function: Screen width/height and available width/height, corresponds to width, height, availWidth, availHeight in JavaScript's screen object.
• Recommendation: If setting this, width and height are required. availWidth and availHeight can be omitted if unknown; the browser will auto-adjust. Try to use real resolutions.
• Examples:
  • 1792x1120,1792x1039
  • 1792x1120

• Function: Physical to CSS pixel ratio, i.e., devicePixelRatio
• Examples:
  • 1
  • 2

• Function: custom-geolocation sets latitude/longitude (navigator.geolocation.getCurrentPosition), block-geolocation blocks location functionality
• Example:
  • --custom-geolocation=110,220,70 (latitude, longitude, accuracy)

• Function: Fake media devices (navigator.mediaDevices.enumerateDevices)

• Function: Spoof browser brand
• Recommendation: If spoofing as a real browser brand, include the user-agent parameter. If using a fictional non-existent brand, user-agent is not needed.
• Examples:
  • --custom-brand="Microsoft Edge" --user-agent="Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/137.0.0.0 Safari/537.36 Edg/137.0.0.0"
  • --custom-brand="fake brand"

• Function: Block port scanning

• Function: Prevent WebRTC from leaking real IP
• Example:
  • --webrtc-ip-policy=disabled

• Warning: Since it's unsigned, run xattr -cr YSbrowser.app on macOS before use.
• Warning: Below are basic parameters. To maintain environment isolation, --user-data-dir is required.
• Warning: To print objects in console, include openConsole, e.g., console.log("openConsole",{}).

chrome --timezone=Asia/Hong_Kong --lang=zh-CN --accept-lang=zh-CN,en --fpseed=121e0opwlltx  --user-data-dir=./my_user_data 

chrome --timezone=Asia/Hong_Kong --lang=zh-CN --accept-lang=zh-CN,en --fpseed=121e0opwlltx  --user-data-dir=./my_user_data --chrome-version=140.0.0.0 --custom-brand=Brave --enable-features=BraveAPI --disable-features=keyboardAPI,NetworkAPI

• ✅ CDP Detection
• ✅ Selenium Signatures
• ✅ Playwright Signatures (only partial removal, patchright still recommended)
• ✅ DrissionPage Signatures

1. Mouse Event Fix: Thoroughly resolved CDP's Input.dispatchMouseEvent defects
2. Shadow DOM Access: Access closed shadow DOM via opshadowRoot
3. Automation Detection Bypass: Eliminated common automation tool signature markers

• Renamed Debugger: debugger → debuging (bypass detection)
• Console Inspection: Bypasses common console property checks
