Session Manager Pro 作成者: EC

Login to the same website with multiple accounts simultaneously using Firefox Container Tabs. Each session has isolated cookies and storage.

Features:
- Create isolated sessions with one click
- Multiple simultaneous logins to any site
- Color-coded tabs show which session you're in
- Move tabs between sessions easily
- Sessions persist across browser restarts

Perfect for managing multiple Gmail, Facebook, or Twitter accounts without logging out.

How it works: Uses Firefox's built-in Container Tabs API to create isolated browsing environments. Each session is a separate container with its own cookies and storage.
