Features & Capabilities

The Sound Adjustment Chrome extension offers a simple, lightweight solution to fine-tune your audio experience directly from your browser toolbar. With intuitive controls for volume (0-100 units), balance (left to right speaker adjustment), and amplification (up to 5x normal volume), users can customize sound output on a per-tab basis.

This add-on is designed for HTML5 audio and video elements, enabling quick sound modifications without affecting other tabs. Volume and balance settings reset upon switching tabs, ensuring personalized audio control tailored to each media session. Note that it currently does not support media embedded within frames. For feature requests or bug reports, the extension's homepage provides a dedicated contact form.

User Reviews

Users like the per-tab left-right balance and the option to boost volume above 100%, noting it works well when functional. However, many reports highlight reliability problems: it often doesn’t work, can reset a tab’s volume to zero or default, and may break after updates. Website compatibility is inconsistent (Spotify, some sites). UI/UX is frequently cited as needing improvement. Overall, the extension is useful when it functions, but reliability and usability issues are common themes.

Pros

Per-tab left/right balance/volume control
Amplification above 100% (volume boost)
Simple, unobtrusive tool focused on audio controls

Cons

Unreliable/inconsistent performance across sites and updates (often does nothing, may require reload)
Tab volumes can reset to zero or to defaults unexpectedly
UI/UX is not very user-friendly and could use improvements (defaults, controls, visibility)
Compatibility issues across websites (e.g., Spotify doesn’t work; Reddit/other sites may be inconsistent)

Saw this extension in Asmongold's clip, thought - oh great, something to adjust left/right channels exists. However, although this simple extension works in Youtube tabs, it doesn't work on Spotify web page. Also, even on Youtube it just doesn't work sometimes (maybe due to to conflicts with other extensions, maybe due to something else), and requires the tab to be reloaded in order to start working.

Is Sound Adjustment 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.

Sound Adjustment does not require any sensitive permissions.

Risk impact analysis details

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.

Sound Adjustment is probably trust-worthy. Prefer other publishers if available. Exercise caution when installing this add-on.
