About JSK Shield
JSK Shield is an open-source ad and tracker blocker for Chrome, Edge and Firefox, licensed under GPL-3.0. It blocks ads, tracking scripts and consent-banner clutter using EasyList, EasyPrivacy and cookie-notice filters, and works the moment you install it - no account, no configuration.
Most blockers ask you to trust them; JSK Shield lets you check. It runs entirely on the user's device, so there is no analytics and no telemetry, and there is no paid allowlist - no advertiser can pay to be let through.
Where it differs is breakage. Every other blocker shows a count. JSK Shield shows the request that was blocked, the exact filter rule that matched, and the list that rule came from, then allows that one request on that one site in a click. When a page breaks, guided recovery offers the least destructive fix first.
