简介

Features:

• Preferred Quality by Default: Set a global preferred quality from 144p through 4320p.
• Premium Codec Preference: Prefer enhanced/premium bitrate variants when YouTube exposes them for the selected resolution.
• Per-Video Manual Overrides: If you select a different quality in YouTube's native menu, the extension respects that choice for the current video only.
• Pause Preferred Quality: Temporarily lets YouTube's native quality behavior control playback without changing your saved preferred quality.
• Firefox for Android: Supports YouTube and YouTube Music.
• Firefox Desktop: Supports YouTube, YouTube Music, and optional Theater Mode on desktop YouTube watch pages.
• Theater Mode (Desktop Only): Optionally switches desktop YouTube watch pages into Theater Mode on page load.
• Active Status Indicator: Shows a green dot on the extension icon when a supported YouTube site is active.
• Dark Mode UI: Minimal, dark-themed popup and responsive options page.
• Compatibility Warning: Displays a local warning if YouTube changes the player APIs required for quality control.
• Privacy Focused: All logic runs locally. No user data is collected or transmitted.

Important Notes:

• Theater Mode is desktop-only and does not run on mobile YouTube or YouTube Music.
• Native YouTube quality selections are treated as temporary per-video overrides. They do not replace your saved preferred quality.
• YouTube frequently changes its player UI and APIs, so occasional compatibility fixes may be needed.
