How to Block Twitch Ads With uBlock Origin (2026)
Key takeaways
- Twitch uses server-side ad insertion (SSAI), so ads travel down the same pipe as the stream and a normal filter list can’t remove them.
- Firefox is the only reliable option today: it runs uBlock Origin’s advanced scriptlet injection needed for the VAFT (“twitch-videoad”) workaround.
- Chrome/Edge on Manifest V3 and uBlock Origin Lite cannot inject the dynamic scriptlets Twitch blocking depends on.
- Expect trade-offs: brief resolution drops, purple screens, or a short “commercial break” placeholder during ad windows.
- Proxy tools like TTV LOL PRO are an alternative, and Twitch Turbo is the only officially ad-free route.
Why uBlock Origin alone can’t block Twitch ads anymore
For years, ad blockers stripped ads by refusing to load requests to ad servers. That works when the ad is a separate file from a known domain. Twitch broke that model by moving to server-side ad insertion (SSAI), also called stream stitching.
With SSAI, Twitch splices the ad segments directly into the same HLS video playlist (the .m3u8 manifest) that carries the live broadcast, and it all comes from Twitch’s own CDN. The live footage and the ad “travel down the exact same pipe,” so there is no separate ad request for uBlock Origin to block. Blocking the pipe would just break the stream.
That is why, if you install a stock copy of uBlock Origin and open Twitch in 2026, you will still see pre-roll and mid-roll ads. Blocking them requires extra logic that rewrites or swaps the stream in real time, and only a browser that allows dynamic scriptlet injection can run it. If you have already read our companion piece on how to block Twitch ads with uBlock Origin, this guide expands it with the 2026 Manifest V3 reality.
Does it block Twitch ads? Browser-by-browser
The single biggest factor is which browser you use, because Chrome’s move to Manifest V3 fundamentally limits what any extension can do to a live stream.
| Browser | Extension | Blocks Twitch ads? | Notes |
|---|---|---|---|
| Firefox | uBlock Origin (full) | Yes, with setup | Retains Manifest V2. Runs the VAFT / twitch-videoad scriptlet. Best current option. |
| Chrome | uBlock Origin Lite | No (unreliable) | Manifest V3 restricts dynamic filtering and custom scriptlet execution needed for SSAI. |
| Edge | uBlock Origin Lite | No (unreliable) | Chromium-based, same MV3 limits as Chrome. |
| Brave | Built-in Shields | Partial / inconsistent | Shields help site-wide but do not reliably strip stitched Twitch stream ads. See our uBlock Origin on Brave setup guide. |
| Firefox forks (LibreWolf, etc.) | uBlock Origin (full) | Yes, with setup | Same MV2 engine as Firefox, so the scriptlet method works. |
How to block Twitch ads with uBlock Origin in Firefox (step by step)
This is the method that still works. You will use Firefox, uBlock Origin’s full version, and one custom scriptlet. Plan on about five minutes.
- Use Firefox (or a Firefox fork). If you are on Chrome or Edge, switch for Twitch. The Manifest V2 engine is what makes this possible.
- Install uBlock Origin. Get the full extension (not Lite) from the Firefox Add-ons store, then pin it to your toolbar.
- Open the dashboard. Click the uBlock Origin icon, then the gear/settings icon to open the dashboard in a new tab.
- Enable advanced mode. On the Settings tab, check I am an advanced user. This unlocks the ability to add custom scriptlet resources.
- Add the VAFT scriptlet. Go to the Filter lists tab, scroll to the bottom, and paste the VAFT (Video Ad-Blocking For Twitch) resource permalink into Import under custom lists, then click Apply changes. This supplies the twitch-videoad logic uBlock needs.
- Add the block filter. Open the My filters tab and add the line below, then click Apply changes:twitch.tv##+js(twitch-videoad)
- Hard-refresh Twitch. Fully close and reopen Twitch, or press Ctrl+Shift+R to clear the cached player.
- Test on a live channel. Watch a busy live stream for a few minutes. During an ad window you should see the player skip, briefly drop resolution, or show a short placeholder instead of a full ad.
What “working” actually looks like
Do not expect a perfectly seamless stream. With SSAI, the blocker is fighting content baked into the video, so you may see a purple screen, a “commercial break in progress” card, a couple of seconds of buffering, or a temporary drop to low resolution while the ad segment plays out silently. That is normal and far better than a 30-second unskippable pre-roll.
If uBlock Origin isn’t enough: proxy and paid alternatives
TTV LOL PRO (proxy method)
TTV LOL PRO is a separate extension (Firefox and Chrome) that takes a different approach: it routes your Twitch playlist request through a proxy in a region where Twitch serves fewer or no ads, then hands the clean stream back to the player. Because it does not depend on scriptlet injection, it can survive on Chrome where uBlock’s method fails.
Caveats to know: the public proxies are volunteer-run and can go down or get rate-limited, which causes buffering or the stream failing to load; you can reduce this by self-hosting your own proxy. It also does not touch banner or display ads, only the in-stream video ads.
Twitch Turbo (official, paid)
The only officially sanctioned way to remove Twitch video ads is Twitch Turbo, roughly $11.99/month. It removes ads site-wide across devices, needs no tinkering, and supports the platform directly. If you watch Twitch daily and are tired of maintaining scriptlets, it is the low-effort route.
Dedicated MV3 blockers
A handful of Manifest-V3-compliant extensions market themselves as Twitch-specific blockers for Chrome. They vary in quality and, like every method except Turbo, are in a constant cat-and-mouse game with Twitch. Treat any “always works” claim with skepticism.
Which method should you choose?
- Want the best free result: Firefox + uBlock Origin + VAFT scriptlet.
- Stuck on Chrome/Edge: try TTV LOL PRO (proxy), and accept occasional buffering.
- Want zero maintenance and to support creators: Twitch Turbo.
Whatever you pick, remember that Twitch actively changes its ad delivery, so no free method is permanent. Bookmark this page and our main uBlock Origin Twitch tutorial, and re-check your scriptlet after any major Twitch update.
FAQ
Does uBlock Origin still block Twitch ads in 2026?
Not by itself. Out of the box it fails against Twitch’s server-side ad insertion. In Firefox, pairing it with the VAFT (twitch-videoad) scriptlet blocks most in-stream ads. In Chrome and Edge, Manifest V3 prevents the required scriptlet injection, so it does not reliably work.
Why does Twitch still show me ads with uBlock Origin installed?
Most likely you are on a Chromium browser (Chrome, Edge, or uBlock Origin Lite), or you have not added the VAFT scriptlet and the twitch.tv##+js(twitch-videoad) filter. Twitch also pushes updates that temporarily break the scriptlet until it is refreshed.
Is it safe or against Twitch’s rules to block ads?
Blocking ads is not illegal, but it does violate Twitch’s terms of service and it reduces the revenue that goes to the creators you watch. The official, TOS-compliant alternative is Twitch Turbo. Consider subscribing to or supporting streamers you enjoy.
What is the purple screen or “commercial break” placeholder?
That is the blocker doing its job. Instead of playing the stitched ad, the workaround suppresses it, leaving a short placeholder or a brief resolution drop until the live feed resumes. It is a normal side effect of fighting server-side ad insertion.
Should I use uBlock Origin or TTV LOL PRO?
Use uBlock Origin with VAFT if you are on Firefox, since it needs no external proxy. Use TTV LOL PRO if you must stay on Chrome or if the scriptlet method breaks, accepting that public proxies can be slow or briefly offline.
