User Reviews

Users largely praise Better Volume Booster for reliably boosting browser audio, even on very quiet laptops, and for being open-source. It’s deemed easy to use, with some noting it just works and outperforms alternatives, and it even offers mono/stereo controls. However, recurring caveats include compatibility issues on certain sites (notably streaming services and YouTube), occasional audio failure or DOA, and a confusing UX with no clear indication that the extension is active. DRM-related playback can be affected on some services.

Pros

Reliable volume boost that many users describe as 'just works' across most sites.
Significantly enhances audio on quiet laptops.
Open-source (FOSS) and well-regarded by users.
Includes useful mono/stereo control for audio output.
Better compatibility than other extensions and handles tricky media cases where others fail.

Cons

Can break video playback or DRM on some streaming sites (e.g., Crunchyroll, HBO Max, YouTube).
Inconsistent performance; some users report audio not working or being DOA.
Not always effective on YouTube (some reviews say it doesn't work there).
User experience can be unclear with no obvious activation status or in-browser indication.

Is Better Volume Booster 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.

Better Volume Booster requires a few sensitive permissions. Exercise caution before installing.

Risk impact analysis details

Critical Allows access to all websites, posing a significant security risk as it can monitor and modify data from any visited site.
High ******* ******* **** *** ****** ***** *** ***** ** ******* **** ********* ********* ** * *********** *****

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.

Better Volume Booster may not be trust-worthy. Avoid installing if possible unless you really trust this publisher.
