Streamblock

About

Streamblock removes ads where they annoy you most: inside Twitch livestreams and YouTube videos – and blocks trackers and banners on every website along the way.
🎯 BUILT FOR STREAMING
• Twitch: Removes pre-roll and mid-roll ads in livestreams without interrupting your stream.
• YouTube: Strips video ads, overlay banners and promotional cards.
• No black waiting screens, no “ad in progress” – just keep watching.
🛡️ TRIPLE PROTECTION
1. Network blocking: 336+ rules (declarativeNetRequest) stop ad and tracking requests before they load.
2. DOM filtering: Removes ad elements directly from the page.
3. Cosmetic filtering: Hides leftover banners, empty ad slots and Flash remnants.
⚡ FAST & LIGHTWEIGHT
• Manifest V3 – modern, efficient Chrome technology.
• Minimal resource usage, no noticeable slowdown.
• Works right after install – no setup required.

🔒 PRIVACY
Streamblock does not sell data and shows no ads of its own. It only collects anonymous, aggregated usage statistics (e.g. active installs) – with no personal data, and you can turn it off anytime from the popup (opt-out).
📋 HOW IT WORKS
1. Install.
2. Open Twitch or YouTube.
3. Watch ad-free. Done.
The popup shows how much has been blocked and lets you disable statistics collection.
Note: Streamblock is an independent project and is not affiliated with Twitch, YouTube or Google.
