No sube demasiado el volumen como para decir que es 600 pero si es bueno, lo recomiendo.

great

It doesnt work anymore

the pc speaker audio was SO QUIET despite the fact that it could output a much louder audio. This add on definitely pushed my speaker to its full potential without pushing it beyond its limit. 5 stars. thank you for this add on

working very good, had to try it out for my laptop, before i had very low sound even on highest system volume on computer. this fix my problem and is easy to use. thank for a good add-on

pretty good

I'm using my headphones as a speaker.

doesn't do what it is supposed to. you can drag those sliders all you want but nothing will change.

It just works.

This add-ons is pretty handy if you want more audio even if you are currently using low system-wide audio settings on your desktop.

Works perfectly on all site, however if possible a dark theme toggle for the extension window would be nice to have.

Toggle for some sound mode types would also be nice like Sound Boost or Vocal Boost in Extension Window along-with some higher percentage sound levels like 200% or 300% etc.

Overall, it's a great add-on for Firefox and highly recommended to anyone looking for a good volume control on web browser.
