Network Speed & Ping Checker di Darren Caldwell

Network Speed & Ping Checker is a lightweight Firefox extension that allows users to measure their internet download speed and ping latency directly within the browser—no need to open external websites like Speedtest.net. With a simple and intuitive interface, this addon fetches a small test file to estimate download speed (in Mbps) and performs a quick image or resource request to calculate ping (in milliseconds). It's designed for speed, privacy, and convenience, making it ideal for users who frequently monitor network performance without leaving their browsing session.
