About this Add-on
app.telemetry Page Speed Monitor has led to dumping load testing without using any performance testing tool as it shows offset and duration of each step for any web page. When a user starts navigating the web page, he can see the load time in the status bar in running mode. Also, it can be installed in Mozilla Firefox and Google Chrome browser. For compatibility and system testing, user can easily track the web page performance and server response time. Here, time is measured in milliseconds in the status bar as shown in the screen shot below:
