Replacements
Listings that take over the same core job as JShelter.
CanvasBlocker
Blocks or fakes the browser APIs most used for fingerprinting.
CanvasBlocker fakes fingerprinting APIs with very granular per-API and per-site settings under MPL-2.0, but it is Firefox focused and lacks a network boundary shield.
NoScript Security Suite
Blocks scripts and active content except on sites you trust.
NoScript blocks scripts entirely except on trusted sites, giving stronger control than wrapping APIs, but many sites break until you grant permissions.
Chameleon
A Firefox extension that spoofs the browser profile and user agent to make fingerprinting harder.
Chameleon is a Firefox extension that spoofs the user agent and browser profile rather than wrapping APIs, and it is not open source.
