## Description

What it does

Suspend Network freezes all network activity in the current tab. In-flight responses are paused mid-stream and new requests are held until you
resume. One click or Ctrl+Shift+U to toggle.

Use cases
<ul><li>Inspect loading states and skeleton screens without racing against fast responses</li><li>Test timeout handling and error states by holding requests indefinitely</li><li>Debug network-dependent UI by freezing the page at any point during loading</li><li>Examine partial page loads and lazy-loading behavior</li></ul>
How it works
<ul><li>Uses filterResponseData to suspend in-flight response streams</li><li>Blocks new requests entirely while suspended</li><li>Badge shows the count of held requests</li><li>Per-tab — other tabs are unaffected</li><li>All requests release cleanly on resume</li></ul>
Privacy &amp; Security
<ul><li>No analytics, no ads, no telemetry</li><li>No data collection or home-dialing — zero network activity of its own</li><li>All processing happens locally in your browser</li></ul>
