## Description

:

🔐 Context Management
Create multiple isolated browsing contexts (containers) with custom names and colors. Each context maintains its own separate session, cookies, and local storage - perfect for managing multiple accounts or separating work from personal browsing.

🌐 Per-Context Proxy Routing
Assign a different proxy to each context. All tabs opened in that context automatically route through the assigned proxy - no manual configuration needed. Supports HTTP, HTTPS, and SOCKS5 proxies.

🎯 Flexible Assignment

Assign contexts to individual tabs for precise control
Assign contexts to entire windows for bulk management
Direct proxy assignment to windows without contexts
Automatic proxy verification with public IP checking
📊 Visual Indicators
Each context displays a colored banner and badge on web pages, making it easy to identify which context you're browsing in at a glance.

📜 Browsing History per Context
Track and review browsing history separately for each context, maintaining clear separation between your different activities.

🛠️ Debug Tools
Optional debug mode shows routing status and provides SOCKS5 testing commands for troubleshooting your proxy configuration.
