So far, so good!

Wowww! I have very cheap speakers plug to my computer and now they do a great job on youtube, it's just unbelievable, and I don't even speak when i plug my headset... Wowww wowww wowww!!
I love also all the presets ready to use, it's straight forward and easy to use.
Thanks a lot Muyor!

Muchas Gracias! Muyor y Equipo de Github & Mozilla, ¡Fantastico!

good

Very well done, light weight, easy to use, and extremely useful

Works perfectly with PEACE and APO. Nice clean bass & no clipping.

Works on all videos.
The panel is slow to open.
Thanks.

Checked c.net for a literal hour not finding what I was looking for with many different quarries to no avail...
Typed one word in the search bar for fire fox extensions, and found this, what I was looking for, with in seconds.
Then created an account for fire fox, verified said account, so I could actually rate this, and give it a good review.
(spent more time creating/activating and reviewing this than I did finding it PLUS! installing it) So long story short? Ty!
