YouTube HD Quality Settings

By: Phase3
YouTube HD Quality Settings automatically applies your saved preferred video quality across YouTube and YouTube Music on desktop and mobile. It also includes an optional automatic "Theater Mode" switch on desktop YouTube pages.

Features & Capabilities

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.

Great addon! Works perfectly on mobile and desktop and does exactly what it says. Although your addon overall has more features than the one I previously used, the other one also had an option to pick a default frame rate (30/60fps) which was really nice. Is this something you could add?

Is YouTube HD Quality Settings Safe?

Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

YouTube HD Quality Settings requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.

Risk likelihood
Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

YouTube HD Quality Settings is recently added, and hasn't been around long enough for us to gather enough data to accurately assess its risk level.
