## Description

KEKW Blocker is a Twitch-focused ad blocker for Firefox.

It blocks Twitch ads primarily by intercepting Twitch's player worker, requesting backup player variants, and switching to a clean stream when ad markers appear. When Twitch playback becomes unstable around ad transitions, the extension also applies stream recovery logic to reduce stalls, loops, and commercial-break overlays.

Key features:
<ul><li>backup player switching for pre-roll and mid-roll ads</li><li>adaptive pre-warming to reduce recovery latency</li><li>stitched ad-segment fallback handling</li><li>buffering and commercial-break recovery</li><li>optional ad-tracking blocking</li><li>auto-claim for Twitch channel points</li><li>signed remote configuration with runtime fallback logic to keep Twitch request constants current</li></ul>
This extension is intended only for Twitch pages and related Twitch media endpoints.
