How to Block Commercials Across Devices, Browsers, and Streaming Platforms

Ads are everywhere — pre-roll video ads, mid-stream TV commercials, banner ads, and autoplay audio. The good news is that blocking most of them is genuinely achievable without advanced technical skills. The approach you take depends heavily on where you're seeing ads, what device you're using, and how much control you want over the process.

Why Ad Blocking Works (and Sometimes Doesn't)

Most digital ads are loaded from third-party servers separate from the content you're actually trying to view. Ad blockers work by intercepting requests to known ad-serving domains before they load — either at the browser level, the app level, or the network level. When an ad request is blocked, the content loads without it.

This works reliably for most web-based ads. It works less reliably for server-side ad insertion (SSAI), a technique streaming platforms increasingly use to stitch ads directly into the video stream before it reaches your device. SSAI is specifically designed to be difficult for traditional blockers to detect because the ad and the content come from the same server address.

Understanding this distinction matters: blocking web ads and blocking streaming TV commercials are genuinely different technical challenges.

Blocking Ads in Web Browsers 🖥️

This is the most straightforward use case. Browser extensions are the most common solution and work on desktop operating systems (Windows, macOS, Linux) with browsers like Chrome, Firefox, Edge, and Brave.

How they work:

• The extension maintains a filter list — a database of known ad-serving domains and URL patterns
• When your browser tries to load a resource, the extension checks it against the list
• Matching requests are blocked before any data loads

Brave Browser takes a different approach by building ad blocking directly into the browser itself rather than relying on extensions, which can offer a performance advantage since there's no extension overhead.

On mobile browsers, the options narrow. iOS Safari supports content blockers through the App Store. Android Chrome has limited native support for extensions, though some third-party mobile browsers (Firefox for Android, for example) do support them.

Key variable: Manifest V3, a Chrome extension platform change, has affected how some ad blockers operate in Chromium-based browsers by limiting how filter lists can be applied dynamically. Firefox has maintained broader support for the older extension model, which is why some users prefer it specifically for this reason.

Blocking Ads on Streaming Services 📺

This is where it gets more complicated. Platforms like YouTube, Hulu, Peacock, and others serve ads differently depending on whether you're using a browser, a dedicated app, or a smart TV interface.

YouTube in particular has been aggressive about detecting and circumventing browser-based ad blockers, frequently updating its ad delivery to stay ahead of filter lists. Some users find that keeping their ad blocker's filter lists updated daily helps — others find the back-and-forth ongoing.

DNS-level and network-level blocking (covered below) can be more effective for app-based streaming ads on some platforms, but results vary significantly by service.

Network-Level Ad Blocking

Tools like Pi-hole (a self-hosted DNS sinkhole) or DNS-based filtering services work at the network level — meaning they can block ads across every device on your home network simultaneously, including smart TVs, phones, and gaming consoles, without installing anything on individual devices.

How it works:

• Your router's DNS is pointed to the filtering service or local Pi-hole instance
• When any device on your network makes a DNS request to a known ad domain, the request is blocked or redirected
• The device never receives a response from the ad server

This approach requires moderate technical comfort — configuring DNS settings, maintaining block lists, and occasionally whitelisting services that break when ad domains are blocked. It's powerful but not plug-and-play.

Cloud-hosted alternatives (some DNS providers offer ad-blocking as a feature) lower the setup barrier but typically offer less granular control.

Blocking Ads on Traditional and Live TV

For cable and satellite TV, ad blocking in the traditional software sense isn't applicable. Options here are different in nature:

• DVR recording lets you fast-forward through commercials after the fact
• Some DVR services offer automatic commercial skip as a feature
• Switching to streaming-only or antenna-based setups changes the ad landscape entirely

Over-the-air (OTA) antenna TV carries commercials baked into the broadcast — no software can intercept those in real time without a DVR buffer.

The Variables That Shape Your Results

No single solution works universally. What actually works for you depends on:

• Where you're seeing ads — browser, app, smart TV, or broadcast
• Which devices you use — desktop, mobile, streaming stick, or smart TV
• Technical comfort level — browser extensions require minimal setup; Pi-hole requires network configuration
• Which platforms you use — some actively fight ad blockers, others don't
• Whether you use premium subscriptions — many platforms offer paid ad-free tiers, which sidestep the technical challenge entirely

Someone who primarily watches YouTube on a desktop browser faces a different problem than someone watching Hulu on a Fire TV Stick or a person dealing with cable TV commercials. The same tool that works perfectly in one context may be completely ineffective in another — and the right combination depends on exactly how and where ads are showing up in your daily routine.
