Is W3Techs Website Technology Information safe?

Clean risk

W3Techs Website Technology Information sends the active tab URL to w3techs.com when you open its popup.

When you click the extension, it reads the current tab's URL and requests https://w3techs.com/siteinfo.html with that URL encoded in the query string. The extension displays the returned site technology information in its popup and does not send non-HTTP(S) tab URLs.
