Twitch Stream Cleaner by unluckxd

Twitch Stream Cleaner is a specialized Firefox extension designed for educational and research purposes to demonstrate browser extension capabilities for HLS stream manipulation and network traffic analysis.

What's new in Version 3:
The ad detection and removal engine has been completely redesigned with a new multi-layered architecture. Based on our latest testing, the new method is highly effective: in 90% of cases, ads are bypassed entirely. In the rare instances where an ad does slip through, it is typically restricted to short, internal Twitch promos lasting 5 seconds or less.

Key Features:
• Multi-layered blocking engine ("Safest First" approach) prioritizing stream stability
• Real-time monitoring dashboard with live statistics
• Privacy protection: blocks trackers (ScorecardResearch, Amazon AdSystem, Comscore)
• Ad-stall guard with automatic player recovery and live-edge seeking
• Automatic UI cleanup and ad overlay management

Technical Approach:
• Service Worker Interception (Layer A): GQL PlaybackAccessToken rewriting (forcing ad-free player types) and response sanitization via a custom Relay Service Worker.
• Context Isolation Bypass (Layer B): Experimental window.Worker hooking to intercept and observe internal Twitch player traffic.
• Network Layer (Secondary): Fail-safe HLS playlist parsing and segment filtering that guarantees playback continuity without synthesizing artificial playlists.
