**Comparing ad blockers?** See [Best YouTube Ad Blockers for Chrome (2026)](/library/best-youtube-ad-blockers-chrome-2026/) for a ranked comparison across extensions.

YouTube and Twitch can't be blocked the same way as banner ads. Standard network-level blocking covers basic ad requests, but both platforms have built fallback delivery paths specifically to work around blockers. A single-layer approach breaks one path and leaves the others intact.

## Why YouTube Is Harder to Block

YouTube serves ads through several distinct paths: pre-roll and mid-roll requests, server-side insertion inside the video manifest (SSAP), overlay banners, bumper clips, and an adblock detection layer that triggers the "ad blockers are not allowed" overlay. Block one and YouTube routes through another.

SuperchargePerformance attacks the problem from multiple sides simultaneously. A `Response.prototype.json` proxy strips ad payloads from player responses before playback. `JSON.parse`/`JSON.stringify` and `TextEncoder.encode` proxies mutate the request parameters that signal "this is an ad". An SSAP interceptor detects server-side ad segments and skips the video forward past them. An XHR proxy catches legacy ad requests. A DOM observer dismisses the "ad blockers are not allowed" enforcement popup if it ever surfaces. The player never gets the chance to render an ad in the first place.

## How Twitch Is Different

Twitch takes a different approach. Ads are embedded directly in the video stream data — the same feed that carries the live broadcast. That means network-level domain blocking doesn't work at all. The request for the stream looks identical with or without ads.

SuperchargePerformance intercepts the stream before the Twitch player processes it, strips the ad segments from the data, and hands back a clean feed. The broadcast plays without the purple "ad in progress" placeholder screen.

## The Toggle

Both YouTube and Twitch are covered by a single Video Ad Blocking toggle in the popup, which is **On by default**. The toggle is independent of the main content blocking slider — you can run them at separate levels or disable one without affecting the other.

## Performance Impact

Video ad blocking uses content scripts that run only on YouTube and Twitch pages. No script runs on other domains. The interception happens before the player starts processing, so there's no observable delay on video load compared to a page without the extension running.
