This is general discussion topic concerning the use of HTML tracking pixels
using customized HTML tags and Javascript web beacons.
Is there any mitigation for this beyond having strict Javascript setting in Tor
Browser and using uBlock Origin and LibreJS plugins?
Is it possible this kind of Javascript exists in graphics or networking drivers?
Could there be javascript based telemetry files with hashed filenames within
hardware driver directories?
Could this be used to capture biometric user data on a desktop UI?
There are hashed javascript files in use by websites that collect biometrics.
