YouTube ad blocker for Chrome

What it removes on YouTube

• Video ads before and during a video, skippable or not.
• Sponsored slots in the home feed, in search results and in the column of suggested videos.
• Promoted banners and shelves on the home page, and the ad panels beside the player.
• The same ads in embedded players, when another site shows a YouTube video.
• If you want, in Focus mode: YouTube Shorts — the shelves, the tab and the suggestions.

YouTube ad blocking is on from the moment the extension is installed. There is nothing to set up.

Why videos keep playing

Many ways of blocking YouTube ads stop requests, or skip an ad once it has started, and YouTube watches for exactly that. Supreme AdBlock avoids the signals it looks for:

• The video servers are never blocked, and neither are the playback reports a normal player sends while you watch; only the report about the ad's state is answered on your device. A player that goes silent is one of the things YouTube counts against you.
• The ads are renamed, not cut out. The change is made to the player's data as text, before the player reads it, so everything else arrives exactly as YouTube sent it.
• Nothing in the page gives it away. The browser functions it works through still describe themselves as the browser's own.
• No tricks that YouTube counts. If an ad still slips through, the extension mutes it and presses YouTube's own Skip button. It never plays an ad at 16× speed.
• No waiting penalty. When YouTube adds its 17-second pause before a video, the wait is cut to a blink.

“Ad blockers are not allowed on YouTube”: what happens

Updated 23 October 2026. Supreme AdBlock steps aside on YouTube for six hours, reloads the page, and the video plays with ads. Blocking resumes by itself six hours after the last time it stepped aside.

It acts when the page shows YouTube's blocker warning, or when the player shows a “Playback ID” error that stays on screen for 8 seconds. It does this at most twice per tab in six hours, never twice within 90 seconds, so a page never reloads in a loop. During the six hours Settings shows YouTube bypass: ACTIVE.

What you can do: wait for the six hours to pass, switch YouTube ad blocking off in Settings at any time (the rest of the protection keeps working), or turn off any second ad blocker on YouTube. While blocking is on, Supreme AdBlock hides that warning and the dark layer over the page; if it cannot step aside, it shows YouTube's warning again so you can act on it. It cannot promise that YouTube will never show it. YouTube decides that, not the extension.

The video stops or buffers after a few videos

Updated 23 October 2026. One known cause is a player that YouTube sees behaving differently from a normal one. Supreme AdBlock is built not to cause that, but it cannot rule it out.

• It does not block googlevideo.com, the video servers, or the playback reports /ptracking. Of the /api/stats/atr reports, only the one that carries the ad's state is answered on your device; the rest reach YouTube as usual. A player that stops reporting is a signal YouTube counts.
• It does not add special request flags to the player by default.
• If a clip never starts (no progress for about 25 seconds), it reloads the page once as a plain client; if the stall returns within three minutes, it steps aside for six hours, as above.

Buffering in the middle of a video on a slow connection is not something the extension fixes. If it keeps happening, reload the page, turn off any other ad blocker, and follow the steps on the support page.

Why it cannot work in the YouTube app on phones and TVs

Updated 23 October 2026. The YouTube apps on phones and TVs cannot run browser extensions. Supreme AdBlock is a browser extension, so it has nothing to attach to there.

It works on youtube.com in a desktop browser that supports Chrome extensions: Chrome, Edge and Brave. On a phone or TV, YouTube Premium is YouTube's own way to remove ads.

What no extension can block

Kept up to date between store releases

YouTube renames its ad fields and page elements often, and a store review takes days. Supreme AdBlock downloads signed filter data about twice a day, with the names of new ad fields, ad panels and Skip buttons, so a change on YouTube can be answered within hours. It is data only: the code that uses it ships inside the extension and never changes from the network.

Block YouTube ads in Chrome in three steps

1. Open Supreme AdBlock on the Chrome Web Store and choose Add to Chrome. It works the same way in Edge and Brave.
2. Reload any YouTube tab that was already open, so the extension can start in it.
3. Play a video. The popup shows how many requests were blocked on the page.

Questions about YouTube

Is the YouTube ad blocker free?

Yes. It is part of Supreme AdBlock, which is free, with no account and no paid tier.

Does it work with Manifest V3?

Yes. Supreme AdBlock was built for Manifest V3, Chrome's current extension platform, so the end of the old platform does not affect it.

Can YouTube stop me from watching?

YouTube says ad blockers go against its Terms of Service. What it does about them is show a warning and, on some accounts, stop playing videos. Supreme AdBlock avoids the signals YouTube looks for, and if playback is refused anyway it steps aside on YouTube for six hours so your videos play.

Does it work in the YouTube app or on a TV?

No. It works on youtube.com in your desktop browser and in YouTube players embedded on other sites. A browser extension cannot reach the YouTube apps on phones, tablets or TVs.

Does it see what I watch?

No. The change happens inside the page, on your device. Nothing about the videos you watch is stored or sent anywhere.

A video won't play. What should I do?

Reload the page first. If two ad blockers are switched on, turn one off: two blockers working on YouTube at once can stall the player. The support page has the other steps.
