Features & Capabilities

Keeps YouTube Music playback at a consistent loudness by reading loudness metadata from the page and applying real-time gain correction with the Web Audio API. Choose from Balanced, Loud, Aggressive, or Quiet presets, or set a custom target between -60 dB and -7 dB. You can enable or disable normalization instantly, and changes from the options page are applied live.

When YouTube Music’s nerd stats panel is visible, the extension adds its own rows showing extension status, post-YouTube loudness, target loudness, and the gain currently being applied. The add-on runs only on music.youtube.com.

Note: You may need to reload or restart YouTube Music after installing the extension or after major playback changes for the normalization to take effect properly.

Is YTM Loudness Normalizer 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.

YTM Loudness Normalizer requires a few sensitive permissions. 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.

YTM Loudness Normalizer may not be trust-worthy. Avoid installing if possible unless you really trust this publisher.
