## Description

This minimal Browser extension blocks user-hostile CSS stylesheets and JS listeners that intercept user actions. The motivation for this extension were news websites which force users to activate JS and force users to activate their telemetry and tracking services when the website was intentionally rendered useless when you don't click "Accept" on their Terms of Service.

Tested in combination with uBlock Origin, which is heavily recommended to block advertisement trackers.
