Browser Core User Guide

User-oriented guide to the browser core. Explains core features, automatic download, system compatibility, and failure handling. No code, only concepts and operations.

📌 Key Highlights

• The core is based on Chromium and is automatically managed by the system; no manual installation is needed.
• The first time you use a specific core version, the system automatically creates a download task. You can view progress in the top Download Manager.
• When downloads fail, follow the recommended order in the Download Manager: Remove task → Check downloaded files → Re-trigger download.
• Deleting core history only affects whether you need to re-download next time. It does not delete browser instance configurations.

🚀 Core Overview

• Chromium-based core, balancing native web experience and fingerprint protection.
• Independent instance environments: cookies, LocalStorage, and SessionStorage are isolated per environment.
• Fingerprint protection coverage: User-Agent, Canvas, WebGL, audio fingerprint, WebRTC, language/time zone, etc.
• Extension management: Download and install extensions, with history and cleanup support.
• Lifecycle management: Create, start, stop, and destroy instances to stay stable and secure.

⬇️ Automatic Core Download

• When you select or use a specific browser core version, the system checks whether it already exists locally.
• If it does not, the system automatically creates a download task and shows progress in the top “Download Manager”.
• Download Manager entry: Cloud-download icon in the top bar. Inside you can view:
  • Download list: Ongoing core or extension downloads with statuses and progress.
  • Core history: Already downloaded core versions, with delete support.
  • Extension history: Already downloaded extensions, with delete support.
• Common statuses: Pending, downloading, extracting, completed, failed, cancelled.
• Actions: Cancel download, remove task, delete downloaded items, check integrity of downloaded files.

Note: After download completes, you do not need to install manually; the system automatically uses that core version on subsequent starts.

🧰 Download Manager Features

• Download list
  • View download progress and status for cores/extensions.
  • Remove failed tasks and re-trigger download.
  • Cancel tasks when network is unstable and retry later.
• Core history
  • View downloaded core versions, size, and download time.
  • Delete downloaded cores so that they will be re-downloaded or switched next time.
• Extension history
  • View downloaded extensions and their install status.
  • Delete extension history to keep the environment clean.
• Check downloaded files
  • One-click check whether downloaded cores and extensions are missing or corrupted.
  • If issues are found, the system cleans invalid records so they can be re-downloaded.

🧩 Core Features (For Users)

• Fingerprint consistency
  • With proper GPU/Canvas/WebGL and UA configuration, the environment is more consistent and stable.
  • Combined with language/time zone and location settings, this reduces abnormal recognition caused by mismatched environment and network.
• Isolated environments
  • Each instance has its own data storage and proxy config, enabling secure multi-account operation.
• Extension control
  • Supports extension download and management, reducing unnecessary extension fingerprint leaks.
• Performance and stability
  • Core updates include security patches and performance optimizations for long-running stability.

🖥️ System Compatibility and Version Suggestions

• Supported platforms: Windows, macOS, Linux (64-bit recommended).
• Version selection: Prefer verified core versions for compatibility and stability.
• GPU and rendering: GPU/renderers differ across platforms. It is recommended to use “Smart Generate” to match platform characteristics.
• Resource consumption: Newer cores may require more memory and disk space. Ensure adequate system resources.
• Proxy and network: If you use a proxy, make sure the download source is reachable. In case of failure, try switching network or temporarily disabling the proxy to download.

🛠️ Handling Download Failures (Recommended Order)

1. Check error details in the Download Manager to identify the cause (network/space/permissions).
2. Click “Cancel” or “Remove” on failed tasks and retry after the network is restored.
3. Run “Check downloaded files” to clean invalid core or extension records.
4. In “Core History”, delete the corresponding core version and re-trigger download.
5. Confirm you have enough disk space (especially for download and extraction directories).
6. Check whether firewalls or security software are blocking download or extraction.
7. If it still fails, try another network or temporarily disable the proxy and retry.

Note: Deleting core history does not affect saved browser instance configurations; it only causes the core to be re-downloaded next time.

✅ Daily Usage Suggestions

• Stick to verified core versions to reduce web compatibility issues caused by frequent version changes.
• Regularly clean unused cores and extension history to keep disk space and the system clean.
• Use “Check downloaded files” to quickly find and clean corrupted or missing items.
• In multi-account scenarios, configure language, time zone, and UA per instance to match the proxy location.
