uBlock Origin Not Working on Chrome? Watch YouTube Ad-Free Without It [2026]

Updated for 2026 · ~6 min read

If uBlock Origin stopped working on Chrome — greyed out, disabled, or gone from your toolbar — you're not doing anything wrong and your install isn't broken. Google turned off the extension platform it relied on. Here's exactly what happened, and a no-install way to watch YouTube ad-free without any blocker at all.

The short version: in late 2024 Google removed uBlock Origin from the Chrome Web Store, and in July 2025 Chrome permanently disabled the remaining Manifest V2 extensions — the older extension platform uBlock Origin depends on. If you're on Chrome (or any Chromium browser like Edge), that's why the classic uBlock Origin no longer filters anything. It's not a bug you can fix by reinstalling.

Why uBlock Origin stopped working

Chrome extensions run on an API platform, and Google spent years migrating from "Manifest V2" (MV2) to "Manifest V3" (MV3). Manifest V3 changes how content-blocking extensions are allowed to inspect and filter network requests — replacing the flexible, on-the-fly filtering that made uBlock Origin so effective with a more limited, pre-declared ruleset.

uBlock Origin's author chose not to cripple the full extension to fit those limits, so the full version stayed on MV2 — and once Chrome disabled MV2 for good in mid-2025, it simply stopped running. You may still see it listed in chrome://extensions as disabled with a note that it's no longer supported.

The no-extension fix: a web player in a tab

Open fyta in Chrome — it's a free, web-based YouTube player. There's nothing to install into the browser, no extension platform to depend on, and no account to sign in to. You get a clean, distraction-free player that auto-skips the sponsor and self-promo segments creators bake into their videos, using the crowd-sourced SponsorBlock database. Because it's a web page, Manifest V3 has nothing to disable — there's no extension in the equation at all.

Step by step in Chrome

1. Open a new tab and go to fyta.cannappy.org.
2. Search for a video, or paste a YouTube link into the box.
3. Press play. Sponsor and self-promo segments are skipped automatically as you watch.
4. Want it one click away? Pin the tab or bookmark it to your Chrome bookmarks bar.

Why not just reinstall or find a patched build?

You'll find forum threads suggesting registry tweaks, enterprise-policy flags, or "still works" builds. Most of those either stopped working when MV2 was fully disabled in July 2025, or rely on settings Google is closing off. Even where a workaround limps along, you're maintaining a fragile setup that breaks with the next Chrome update — the exact treadmill people are tired of. A web player skips that entirely because there's no extension to keep alive.

uBlock Origin vs. a web player, in 2026

What about uBlock Origin Lite?

Google points people to uBlock Origin Lite (uBOL), a Manifest V3 build the same author ships. It's a real project, but it's deliberately limited by MV3's pre-declared ruleset — and it does not skip the creator sponsor segments baked into videos. For YouTube specifically, many people find it weaker than the tool they lost. We compare the honest options in our guide to the best uBlock Origin alternative after it got disabled.

If you still start every session on YouTube

Some people begin on YouTube itself. For that there's an optional free "Watch on fyta" browser extension that adds a one-click button to open the current video in fyta's clean player. It's a convenience shortcut, not a requirement — the player works on its own with nothing installed. Everything else — built-in search, the share ad-free link button, and the Jump back in resume feature — lives in the web player.

Works the same across your devices

Because fyta runs in the browser, the same approach works on a Chromebook, a Windows PC, a Mac, or your phone.
