1. Intelligent URL Normalization

URLs that are functionally identical often look different due to tracking parameters (?utm_source=...), session tokens, or fragment identifiers. The extension normalizes URLs before comparison — removing a configurable list of known tracking parameters (UTM, fbclid, gclid), stripping fragments, normalizing protocol and trailing slashes — ensuring that the same page with different tracking URLs is correctly identified as a duplicate.

2. Focus-History Aware Duplicate Resolution

When a duplicate tab is detected, the extension keeps the tab with the most recent active focus (the "last touched" tab) rather than blindly closing the newer tab. This prevents losing the tab the user is actively working in when, for example, clicking a link that opens a tab that was already open in the background.

3. Whitelist for Intentional Duplicates

Some power users intentionally open the same URL in multiple tabs (e.g., two windows of the same Google Doc for reference). The extension supports per-URL and per-domain whitelists — allowing specified domains or URLs to bypass deduplication so intentional duplicates are preserved.

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.
