Blackice

Intrusion countermeasures for the web. Blocks ads, trackers, miners, and more — easy on CPU and memory.

blackice is xvoidsx's Manifest V3 ad and tracker blocker, dressed in nightshadeNeon — deep blacks, neon pink, phosphor green. Ads, trackers, and annoyances are blocked with declarative filter lists processed entirely on your device. No accounts, no analytics, no remote code: everything the extension runs ships inside the package, and protection stays current with weekly filter rebuilds. Features: • Efficient Manifest V3 blocking with declarativeNetRequest • Element picker and zapper for your own cosmetic filters • Per-site control — block, allow, or strict mode • nightshadeNeon popup, dashboard, and first-run experience Free and open source (GPLv3), from xvoidsx — made for the open web.
