Is Mobile Friendly Test - cmlabs Tools safe?
Mobile Friendly Test sends the tested page URL to Google PageSpeed with an embedded API key.
When the extension runs a mobile-friendly analysis, it reads the active tab URL, reduces it to a base URL, and sends it to Google's PageSpeed Online API. The request includes a hardcoded API key and returns PageSpeed results that the extension stores locally for display.
