User Reviews

Overall, reviews praise the extension for its strong volume boost and for generally delivering the promised functionality with a simple, easy-to-use interface. The main caveat is compatibility: its effectiveness varies by site, with some sites working and others not. A few users also report reliability issues on certain platforms. Despite these concerns, the sentiment is largely positive, especially for users needing louder audio in low-volume content.
Pros
  • Significant volume boost for dialogues, podcasts, and music
  • Generally does what it promises and works for many sites
  • Simple and straightforward to use
  • Helpful for listening in low-volume scenarios
Cons
  • Inconsistent performance across sites; not all sites are supported (e.g., IMDB and others may not work)
  • Some users report it doesn’t work at all or is unreliable on certain sites

Is 600% Sound Volume 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.

600% Sound Volume 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.

600% Sound Volume may not be trust-worthy. Avoid installing if possible unless you really trust this publisher.
