How to Block Twitch Ads with uBlock Origin (2026 Guide)

uBlock Origin is the gold standard for blocking ads almost everywhere — but Twitch is its toughest opponent. If you’ve added uBO and still get mid-roll ads, you’re not doing anything wrong: Twitch serves video ads in a way that ordinary ad blockers can’t touch. Here’s why, and the method that still works in 2026.

Why uBlock Origin doesn’t block Twitch ads by default

Twitch uses Server-Side Ad Insertion (SSAI). Instead of loading ads from a separate ad server that uBlock Origin can recognize and block, Twitch stitches the ad directly into the live video stream on its own servers before it ever reaches your browser. To uBlock Origin, the ad and the stream look like the same thing.

That’s why uBlock Origin still happily removes Twitch’s banner ads, display units, and trackers — those come from blockable sources — but the in-stream video ads sail right through. Blocking them requires a Twitch-specific helper script that swaps the video feed during an ad break, not just a filter list.

Important: This trick needs the full uBlock Origin extension. The lighter uBlock Origin Lite does not support the advanced settings and custom resource scripts this method relies on. If you only have uBO Lite installed, you’ll need the full version.

The method that still works in 2026

This uses uBlock Origin’s advanced mode plus a community "video ad" scriptlet. Follow it exactly:

1. Open uBlock Origin’s dashboard. Click the uBO icon → the gears/settings icon to open the dashboard.
2. Enable advanced user mode. On the Settings tab, tick "I am an advanced user."
3. Set the user resource location. Open the advanced settings and find userResourceLocation, then replace unset with the URL of the current Twitch ad scriptlet (the community vaft-ublock-origin.js file from the TwitchAdSolutions project).
4. Add the filter. Go to the My filters tab and add:

   twitch.tv##+js(twitch-videoad)

5. Apply changes and hard-refresh Twitch (Ctrl/Cmd + Shift + R).

If a stream still shows ads, fully close and reopen the tab, or restart the browser so the scriptlet reloads.

The big caveat you need to know

On March 5, 2026, the main community repository behind these workarounds — TwitchAdSolutions — was archived and made read-only. The existing scripts (like the vaft release) still work for now, but they are no longer actively maintained against Twitch’s constantly changing ad system. That means:

• The method can break at any time without a fix.
• You may need to periodically update the scriptlet URL if a maintained fork appears.
• Reliability varies by browser — Firefox currently offers the most consistent results, with Chromium browsers more hit-or-miss.

In short: enjoy it while it lasts, but don’t be surprised if Twitch wins a round.

What to do when uBlock Origin stops blocking Twitch ads

If ads suddenly come back:

• Hard-refresh and restart the browser — the simplest fix, and often all you need.
• Re-check the scriptlet URL in userResourceLocation; a stale link is the most common cause.
• Confirm you’re on full uBO, not uBO Lite.
• Try Firefox if you’re on a Chromium browser and having no luck.
• Consider a different layer — some users pair uBO with a streaming-focused blocker, or watch via a third-party Twitch front-end, when the scriptlet route fails.

The honest bottom line

uBlock Origin remains excellent for Twitch page ads and trackers, and the scriptlet method can still kill in-stream video ads in 2026 — but it’s a moving target, and the community project that powered it is no longer maintained. Set it up, keep Firefox handy as your most reliable option, and expect occasional maintenance.

Frequently asked questions

Does uBlock Origin Lite block Twitch ads?
No. The Lite version lacks the advanced mode and custom scriptlet support this method requires. Use full uBlock Origin.

Is blocking Twitch ads against the rules?
Twitch discourages it, and ad revenue supports your favorite streamers — many viewers subscribe to their main channels (which also removes that channel’s ads) to support them directly.

Why does it work on Firefox but not Chrome?
Browser differences in how extensions and scriptlets run make Firefox the more dependable platform for these Twitch workarounds in 2026.
