CLUSTER ADS-BLOCKS-BROWSER-2 · 16 ENTRIES · EARLIEST ENTRY 2019-07-13

Privacy-first ad-blocking browsers

This cluster consists of privacy-focused web browsers that block ads and trackers, often including private search, customization, and on-device data retention. Entries appeared intermittently from December 2013 to July 2026, with a few in 2019 and a more concentrated set from late 2024 through mid-2026. Among them, LibreWolf, Waterfox, and FireDragon lead on traction, each with 0 stars in activity signal.

Each bar is the month a member carries, which is a creation date where the source published one and a crawl date otherwise. Nothing in the index was found before 11 August 2026, and coverage broadened sharply on 14–15 August, so a bar from then on reports how much we found that month, not how much was built; an earlier bar reports how far back a member's own source dated it — not how long we have been watching.
