YouTube does not always auto-select HD quality for videos, forcing users to manually change quality every time. This extension solves that by letting users set a preferred quality once, which is then applied automatically to all YouTube videos.

User installs the extension → opens the popup/options page → selects desired default video quality (e.g., 1080p) and optionally enables autopause → extension injects a content script on YouTube that uses the YouTube player API (setPlaybackQualityRange) to automatically apply the chosen quality whenever a video loads.

目标用户: YouTube viewers who want consistent video quality without manual intervention / Users on connections where they want to lock to a specific resolution (e.g., always HD or always lower bandwidth)

The fetch to api.megaxt.com/qualityList is dead code (unreachable due to early return on line 117 of background/main.js), so the remote quality list endpoint is never actually called.
The embedded.js content script injection is also dead code (gated behind `if (false && ...)` on line 44 of background/main.js).

付费分析

未识别到付费功能

No premium features, subscriptions, payment gates, billing APIs, or upgrade prompts exist in the extension source. The quality list (144p to 8K) and autopause are all freely accessible without any paywall. The 'pro' keyword hit in static_scan is a false positive from verified_contents.json (signed hash data) and 'process' in options.html.
