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 mid-clutch, you’re not doing anything wrong: Twitch serves video ads in a way that ordinary ad blockers simply can’t touch. Below, we break down exactly why that happens, the scriptlet method that still works in 2026, the big changes you need to know about (a Manifest V3 shake-up and an archived community project), and the alternatives worth trying when uBO alone isn’t enough.
Quick Answer
Plain uBlock Origin can’t block Twitch’s in-stream video ads because Twitch stitches them into the live feed on its own servers (SSAI). To kill them you need the full uBO (not uBO Lite), advanced mode enabled, and a community “video ad” scriptlet added as a custom resource. It works best in Firefox in 2026 — but the main community project behind it was archived in March 2026, so treat it as a temporary fix and keep a backup plan ready.
Why uBlock Origin doesn’t block Twitch ads by default
Twitch uses Server-Side Ad Insertion (SSAI), sometimes called “stream stitching.” Instead of loading ads from a separate ad server that uBlock Origin can recognize and block, Twitch splices the ad directly into the live video stream on its own servers before it ever reaches your browser. The ad segment and the content segment arrive from the same Twitch CDN, over the same connection, wearing the same URL. To uBlock Origin, the ad and the stream look like one and the same thing.
That’s why uBlock Origin still happily removes Twitch’s banner ads, display units, and trackers — those come from separate, blockable sources — but the in-stream video ads sail right through. There’s no distinct request to filter, no ad domain to blocklist. Blocking these requires a Twitch-specific helper script that detects an ad break and swaps the video feed (often to a lower-resolution ad-free backup stream) for those few seconds, not just a static 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 — which is increasingly the default on Chrome (more on that below) — 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 (the vaft release from the TwitchAdSolutions project). Follow it exactly:
- Open uBlock Origin’s dashboard. Click the uBO icon → the gears/settings icon to open the dashboard.
- Enable advanced user mode. On the Settings tab, tick “I am an advanced user.”
- Set the user resource location. Open the advanced settings and find
userResourceLocation, then replaceunsetwith the URL of the current Twitch ad scriptlet — the communityvaft-ublock-origin.jsfile from the TwitchAdSolutions project. - Add the filter. Go to the My filters tab and add:
twitch.tv##+js(twitch-videoad) - 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. Because the project is now archived (see below), double-check that a maintained fork hasn’t replaced the original script URL before you assume the method is broken.
The big caveat: TwitchAdSolutions was archived
On March 5, 2026, the main community repository behind these workarounds — TwitchAdSolutions — was archived and made read-only, with the maintainer stating they were no longer interested in the project. 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. In practice that means:
- The method can break at any time, and there’s no longer an official maintainer racing to patch it.
- You may need to periodically switch to a community fork (several have appeared) and update the scriptlet URL accordingly.
- 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. Vet any fork you point uBO at, since you’re granting it the ability to run a script on the Twitch page.
Manifest V3, Chrome, and why your browser matters
There’s a second, bigger shift working against Chrome users. Google completed its transition to Manifest V3, which replaced the flexible webRequest API that content blockers depended on with the more limited declarativeNetRequest API. The upshot: the full uBlock Origin is effectively deprecated on Chrome, and many Chrome users are nudged toward uBlock Origin Lite — which, as noted, can’t run the custom Twitch scriptlet at all.
The browsers, in 2026 terms:
- Firefox — not built on Chromium and still supports the full
webRequestAPI, so full uBO runs unrestricted. This is the most dependable platform for the Twitch scriptlet method. - Brave — still runs full uBO for now and has its own built-in Shields, though the Twitch scriptlet is less consistent than on Firefox. If you’re a Brave user, our uBlock Origin on Brave setup guide walks through whether you even need the extension on top of Shields.
- Chrome — the weakest option. Full uBO is being phased out, and uBO Lite lacks the permissions to manipulate the Twitch video stream.
If Twitch ad-free viewing is a priority, switching to Firefox is the single most effective change you can make.
Alternatives when uBlock Origin isn’t enough
uBO’s scriptlet route is free but fragile. Here are the main alternatives people pair with it or use instead in 2026:
- TTV LOL PRO — a proxy-based extension that routes the stream through a server in a region without Twitch ads. It removes most livestream ads but can add a few seconds of latency, and it doesn’t touch banner ads or VOD ads. Many users get the best results combining it with uBlock Origin.
- Purple Ads Blocker — works on a similar proxy principle, fetching an ad-free stream from another location.
- Streamlink — pulls the stream into an external player like VLC or MPV, bypassing the Twitch web player and its ad insertion entirely. More technical to set up, but robust.
- Subscribe to the channel — a channel subscription removes that channel’s ads for you while directly supporting the streamer.
- Twitch Turbo — the only officially sanctioned, permanently stable option. At around $11.99/month it removes pre-rolls, mid-rolls, and house ads across every stream, no scripts required.
Twitch ad-blocking methods compared
| Method | Works in 2026? | Difficulty | Notes |
|---|---|---|---|
| uBO alone (default filters) | No (video ads) | Easy | Blocks banners/trackers, not SSAI in-stream ads |
| Full uBO + vaft scriptlet | Mostly (unmaintained) | Moderate | Best on Firefox; may need fork updates |
| TTV LOL PRO (proxy) | Yes (usually) | Moderate | Adds some latency; pair with uBO |
| Streamlink + VLC/MPV | Yes | Advanced | Bypasses web player entirely; no chat |
| Channel sub / Twitch Turbo | Yes (guaranteed) | Easy (paid) | Officially supported; supports streamers |
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 or archived link is the most common cause. Swap to a maintained fork if needed. - Confirm you’re on full uBO, not uBO Lite.
- Try Firefox if you’re on a Chromium browser and having no luck.
- Add a second layer — many users pair uBO with TTV LOL PRO, or fall back to Streamlink, when the scriptlet route fails.
Key Takeaways
- Twitch’s SSAI stitches ads into the stream itself, so plain uBO can’t block in-stream video ads.
- The working method needs full uBlock Origin, advanced mode, and the community
vaftscriptlet. - TwitchAdSolutions was archived on March 5, 2026 — the script still works but is unmaintained.
- Manifest V3 makes Chrome unreliable for this; Firefox is the most consistent platform.
- TTV LOL PRO, Streamlink, a channel sub, or Twitch Turbo are solid fallbacks.
The 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 now that the community project is archived and Manifest V3 is squeezing Chrome. Set it up on Firefox, keep TTV LOL PRO as a backup, and if you just want it to work forever, a channel subscription or Twitch Turbo is the only guaranteed route.
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. You need full uBlock Origin, which in 2026 means running it on Firefox or Brave rather than Chrome.
Why does the method work on Firefox but not Chrome?
Firefox still supports the full webRequest API that full uBO relies on, while Chrome’s Manifest V3 rollout deprecated it and pushes users toward uBO Lite, which can’t run the Twitch scriptlet. Browser differences in how extensions execute scripts make Firefox the more dependable platform.
Is the TwitchAdSolutions script safe to keep using?
The archived vaft script still functions for many users, but because it’s no longer maintained it can break without warning. If you point uBO to a community fork instead, vet it first — you’re allowing it to run code on the Twitch page.
What’s the best alternative if the scriptlet stops working?
Most people switch to TTV LOL PRO (a proxy extension, best paired with uBO) or Streamlink with VLC/MPV. For a permanent, officially supported fix, subscribe to the channel or buy Twitch Turbo.
Is blocking Twitch ads against the rules?
Twitch discourages it, and ad revenue helps support your favorite streamers. Subscribing to a channel removes that channel’s ads and supports the creator directly — a good middle ground if you’d rather not fight the ad system.
Do I still need uBlock Origin if I use a proxy blocker?
Yes. Proxy tools like TTV LOL PRO target in-stream video ads but don’t remove banner ads, display units, or trackers. Running uBlock Origin alongside them covers the rest of the page.
