Browser Support

The application supports both Chromium-based browsers (using a common JSON format) and browser-specific formats like Safari's plist and Firefox's SQLite database. While not every browser has been tested, the application is designed to be easily extensible.

If you encounter issues with a specific browser:

1. Check the browser's bookmark file location in the PathManager class
2. Verify the bookmark file format in the BrowserParsers class
3. Add or modify the appropriate paths and parsers as needed

Usage

Run the application:

python main.py

2. Select a browser from the dropdown menu to view its bookmarks.

3. Use the Network tab to:

   • Connect to other BookmarkManager instances
   • Share bookmarks with other computers
   • Enable two-way sync
   • View connection status and details

4. To share bookmarks:

   • Connect to another instance using either manual connection or auto-discovery
   • Use "Share Bookmarks" to share all bookmarks (default) or selected bookmarks
   • Use "Sync Bookmarks" to perform a two-way sync between machines

5. To manage bookmarks:

   • Right-click on bookmarks or folders to access context menu
   • Add, edit, or delete bookmarks and folders
   • Drag and drop to organize bookmarks
   • Use the search bar to find specific bookmarks

Security

The application implements several security measures to protect your bookmarks:

• End-to-end encryption for all network communication
• Secure key exchange using NaCl
• Message signing with HMAC
• Rate limiting and connection limits
• IP blacklisting for suspicious activity
• Automatic cleanup of stale connections
• Protection against common attacks (DDoS, replay, etc.)
