Executive Summary & Commercial Scope

MultiAccount Switcher is a browser session isolation and multi-account management extension engineered by Pasindu Piumal for a digital marketing agency on Fiverr managing 12 client social media accounts. The agency was spending 90 seconds per account switch (logout → login cycle), losing 30+ minutes daily to authentication friction. The extension maintains completely isolated cookie sessions for each account and switches between them in under 2 seconds via keyboard shortcut.

1. Full Cookie Set Snapshotting

When a user logs into an account with the extension active and clicks "Save Profile", the extension captures the complete cookie set for that domain — including all session tokens, remember-me cookies, CSRF tokens, and authentication cookies. This snapshot is stored per profile in encrypted chrome.storage.local. On switch, the current cookie set is replaced with the target profile's snapshot.

2. Per-Tab Independent Account Contexts

Unlike browser profiles (which are all-or-nothing), the extension supports different accounts in different tabs simultaneously — using Chrome's cookie partition keys and tab-specific cookie override APIs to inject different authentication cookies per tab. A developer can browse their personal account in one tab and a client account in another.

3. Session Expiry Re-Login Detection

Authentication sessions expire. The extension monitors HTTP response codes — detecting 401 Unauthorized and 302 redirects to login pages — and immediately alerts the user when a stored account session has expired, prompting them to re-login and refresh the saved cookie snapshot.

4. Zero-Leak Real-Time Telemetry & WebSocket Stream

Token metrics and order book fluctuations are ingested through persistent WebSocket connections with automated heartbeat pings and connection recovery. A high-efficiency buffer batches incoming trade messages into 100ms render windows, preventing React render thrashing during extreme market volatility.
