Replacements

Listings that take over the same core job as CanvasBlocker.

  • JShelter

    Wraps browser APIs to reduce JavaScript fingerprinting and tracking.

    JShelter wraps a wider set of browser APIs under GPL-3.0 and adds a network boundary shield, but its noise can sometimes make a browser more distinctive.

  • Chameleon

    A Firefox extension that spoofs the browser profile and user agent to make fingerprinting harder.

    Chameleon spoofs the user agent and wider browser profile rather than faking individual APIs, stays Firefox focused, and is not open source.
