Customize and improve the Niconico video website UI

Niconico's interface has cluttered ads, premium promotions, and layout changes that users find undesirable. This extension provides granular control over UI elements and adds useful video features.

User installs extension -> Extension injects content scripts into nicovideo.jp pages -> User opens extension popup to toggle desired features -> Changes are saved to chrome.storage.sync -> Content scripts apply CSS modifications and add UI elements/features to the page immediately

Target users: Niconico video platform users who want a cleaner UI / Japanese video sharing platform users seeking ad/premium content removal / Users wanting enhanced video playback features

Main bundle (index.ts-Su0R_G0H.js) is 3.5MB minified and could not be fully analyzed for all feature implementations. Some feature behaviors inferred from popup settings and CSS selectors.
FFmpeg WASM binary (24MB) present but not analyzed for actual usage patterns.
Cannot verify if video download/upscaling features work without actual Niconico account and video content.

Monetization

No paid features detected

The extension is completely free with no paid features, subscriptions, or payment integrations. The 'hidePremiumSection' setting refers to hiding Niconico's own premium/advertisement sections on the website, not gating extension features behind a paywall. All features listed in the popup (video download, upscaling, PiP, screenshot, classic layout, etc.) are freely available and toggleable.

Confidence: 95
Payment platform: --
Source: AI / High
Login required: No
Reason: The extension operates entirely client-side on nicovideo.jp pages. It uses chrome.storage.sync for local settings persistence. There is no code implementing login, authentication, or session management. While Niconico itself may require login for some features (like posting comments), the extension's core functionality (UI customization, hiding sections, video download/upscaling helpers) works without requiring the user to log into the extension or create an account with the extension developer.
