The Best uBlock Origin Alternative for Chrome in 2026

If you opened Chrome recently and found that uBlock Origin was disabled — or simply stopped catching ads — you are not alone. With the move to Manifest V3, Google changed the rules that browser extensions must follow, and the classic version of uBlock Origin relies on an API that Chrome is phasing out.

Why uBlock Origin stopped working in Chrome

uBlock Origin was built on Manifest V2, which let extensions inspect and block network requests on the fly using the webRequest API. Manifest V3 replaces that with declarativeNetRequest, which asks extensions to register their blocking rules in advance and caps how many they can use. That shift is what broke the original uBlock Origin in Chrome. It still works in Firefox, but Chrome, Edge and other Chromium browsers now require an MV3-compatible blocker.

What to look for in an alternative

• Built for Manifest V3 — so it keeps working after Chrome disables MV2 extensions.
• Blocks ads everywhere, including YouTube, Twitch and embedded video, not just a handful of big sites.
• Lightweight — a blocker should make pages faster, not slow the browser down.
• Privacy-friendly — your settings should stay on your device.

All Block: a drop-in replacement

All Block is built from the ground up for Manifest V3, so it keeps blocking ads reliably in Chrome and Edge. It removes banners, pop-ups and video ads across the web, skips ads on YouTube, blocks trackers, and adds a Page Safety Scanner that warns you about dangerous links. It is free, lightweight, and works right out of the box — no rules to configure.

If uBlock Origin has become unreliable on your machine, adding All Block to Chrome takes a few seconds and restores a clean, ad-free web.
