Inspect HTTP traffic and alert on local-network probes — side panel, toolbar badge, and desktop notifications. See what websites are doing behind the scenes A website can make dozens or even hundreds of network requests while you are simply viewing a page. Most requests are expected, but some may involve third-party services, reveal unexpected tracking activity, probe local network resources, or communicate with services you did not know were running. NetScope gives you real-time visibility into browser network activity directly inside Firefox. Monitor HTTP traffic, investigate suspicious connections, inspect requests and cookies, and control network activity from a convenient dark sidebar — without leaving the page you are browsing. Detect possible local-network probing One of NetScope key capabilities is monitoring activity that may indicate attempts to probe local network resources. Instead of wondering what a website is doing in the background, you can observe network activity as it happens and investigate unexpected connections. NetScope is designed as an inspection and research tool for privacy-conscious users, web developers, penetration testers, and security researchers.
