Webpage tracking using only CSS #918

Closed sebast889 closed 6 years ago

I came across this https://github.com/jbtronics/CrookedStyleSheets

It can track some things like fonts installed on user OS, browser resolution and if the user hovers over a link. I'm wondering if there is something uMatrix can do to protect against this without fully disallowing CSS requests.

Block CSS.

Is there no other way to protect against this type of tracking without blocking CSS totally?

Use the Tor browser.

If you think something can be done which is well within the scope of uMatrix's purpose, please share. Closing for now.

It's already being done by various fingerprinting methods, so this is not news anymore.
