Take a Speedtest directly from your Google Chrome toolbar to quickly test your internet performance without interruption. Measure how fast the pages you visit load with Web Speed.

Features:
– Get your ping, download, and upload speeds within seconds
– Measure how fast websites load

Permissions:
Chrome will ask for permission to “Read and change all your data on the websites you visit”. Speedtest also measures how fast websites load with Web Speed, and it uses this permission to know how long it takes a given website to load. You can disable Web Speed in the extension settings.
