It's fast, free, and provides information on your download and upload speeds, along with system information. Broadband Speed Test and Diagnostics is extremely simple to operate. After installation, you'll find a new option on your Firefox Tool's menu. It provides four quick one-click options that are well-labeled and easy to understand.
The four options are split between Internet and Broadband tests. The first has download and upload tests, which not only show you the speed of your Internet capabilities but also where you fall in the range from slow to fast. For Broadband, you can run a short diagnostic test that reports if select elements pass or fail. It also checks your browser's home page to test if it's responding. You don't need any special skills to understand the simply presented results. The Show Configuration button relays basic information about your IP address, Ethernet adapters, and Windows IP data.
