active
significant_divergence
Selected Choose this fork if the goal is anti-ad-surveillance behavior with explicit ad collection/vault workflows; choose upstream uBlock Origin if you want the leanest, least surprising blocker with the freshest mainstream fixes and lower operational risk.
el1t/uBlock-Safari
stale
significant_divergence
Choose this fork only if Safari support is the deciding factor. For everyone else, upstream uBlock Origin is the safer choice because it is actively maintained and materially newer.
Choose this fork if you want uBlock Origin adapted for Manifest V3 on Chromium and value the extra packaging/install work. Stick with upstream if you want the broadest, most mature release path and the latest fixes across the full project first.
brave/uBlock
active
significant_divergence
Choose this fork if you want a maintained Brave downstream with automation around syncing and PR handling. Choose upstream if you want the canonical project with the least downstream policy and merge complexity.
Windscribe/uBlock
stale
significant_divergence
Choose this fork only if you specifically need its Windscribe-specific modifications. For most users, upstream uBlock Origin is the safer default because this fork is stale and materially behind on active maintenance and recent blocker features.
Prefer this fork if you want a slightly customized uBlock Origin with dev-build convenience and a few extra advanced controls; prefer upstream if you want the newest fixes, especially around recent MV3 and scriptlet changes, with the least maintenance risk.
TimTheBig/uBlock-plus-plus
slowing
significant_divergence
Choose this fork if you want a Firefox-oriented, more heavily customized uBlock Origin with extra lists and dev-oriented tweaks. Choose upstream if you want the freshest, least risky, most standard uBlock Origin experience.
Prefer this fork if you want a Helium-specific uBlock build with customized defaults and branding. Prefer upstream if you want the latest fixes, broader browser coverage, and the least divergence from stock uBlock Origin.
Alex313031/uBlock-Thorium
stale
significant_divergence
Choose this fork only if you need its browser-fork integration and custom MV3/scriptlet behavior. If you want the most current, broadly supported uBlock Origin, upstream is the safer default because this fork is stale and materially behind.
Synzvato/uBlock
stale
significant_divergence
Prefer upstream unless you specifically need this fork’s old custom behavior or are maintaining legacy code. The fork is highly divergent and stale, so it is better suited to legacy support or archaeology than day-to-day use.
