Replacements
Listings that take over the same core job as NoScript Security Suite.
JShelter
Wraps browser APIs to reduce JavaScript fingerprinting and tracking.
JShelter wraps fingerprinting-related APIs instead of blocking scripts per source, so fewer sites break, and adds a network boundary shield; it is also GPL-3.0.
uBlock Origin
A free, open-source content blocker for browsers that blocks ads, trackers and malware domains with a small footprint.
uBlock Origin blocks ads, trackers and malware domains through filter lists, with an advanced per-site dynamic filtering mode, rather than blocking all scripts by default.
Similar software
