What is Internet Speed Test?

Internet Speed Test is a specially designed add-on for Firefox that provides real-time and average speed testing for internet connections. The add-on uses a toolbar panel for easy testing, and it can measure the speed to the nearest server or a specific one selected by the user. The fastest server is selected for measurement by default, but this can be customized in the settings page. The add-on serves as a user-friendly tool for monitoring internet connection speeds and diagnosing potential speed-related issues.
