Network Speed Monitor av SD9410

Network Speed Monitor is a Firefox extension for desktop and Android that checks your connection at a configurable interval. It displays live connection status, latency in milliseconds, public IP, online time, disconnects, availability, and downtime. It also provides realtime latency history, connection logs, statistics, CSV/PDF exports, and optional online/offline sounds. Monitoring data is stored locally in Firefox. The extension does not use browsing history, page contents, analytics, accounts, or paid services. Google or a custom probe host receives only the connectivity requests required for monitoring.
