Suspend Network by Krzysztof Bogdan

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

• Inspect loading states and skeleton screens without racing against fast responses
• Test timeout handling and error states by holding requests indefinitely
• Debug network-dependent UI by freezing the page at any point during loading
• Examine partial page loads and lazy-loading behavior

How it works

• Uses filterResponseData to suspend in-flight response streams
• Blocks new requests entirely while suspended
• Badge shows the count of held requests
• Per-tab — other tabs are unaffected
• All requests release cleanly on resume

Privacy & Security

• No analytics, no ads, no telemetry
• No data collection or home-dialing — zero network activity of its own
• All processing happens locally in your browser
