Browser-based tools for phone & internet

About

I run MozPK, where I build free tools that help people diagnose phone and internet problems without installing anything — a hardware test for touch screens, speakers, mics and cameras, an internet speed test, and an error code lookup for common device errors. Everything runs in the browser, needs no signup, and is free. I started it after spending years writing troubleshooting guides and realising most people just needed a quick way to test whether the problem was their hardware or their connection.
