NetMon IP & Speed by Ghost Scale

NetMon IP & Speed is a lightweight network status companion for Firefox.

It shows your public IP address, provider, and country with a flag, and automatically measures download speed in the background. The toolbar icon changes color depending on connection health: green for normal, orange for degraded, red for critical drop, gray for no data or error.

Main features:

• Public IP information with country flag
• Automatic download speed monitoring
• Baseline speed calculation from recent measurements
• Dynamic status icon
• Notification on critical speed drops
• Configurable check interval
• Compact popup with optional detailed view
• Local storage only, no accounts

Privacy:

The extension stores speed history and settings locally. It uses third-party endpoints only to determine your public IP and perform speed measurements. See the privacy policy for details.
