I use this to fine-tune music on YouTube (bass specifically). It does that job perfectly, hence the score. However this Add-on breaks a lot of other video related services like twitch.tv and certain file/flash types (.webm) for me. You will have to turn it off manually in the Add-on menu and hard refresh the page to get everything working properly again. @Dev: A quick on/off button when clicking the icon would be great for this reason. Happy holidays.

I like my "Audio Equalizer" by Muyoo a lot because I can boost the bass inside my "Firefox" application!

Excellent tool, preset saving possibility is very usefull !

Спасибо! Вы спасли мои вкладки с музыкой в любимой firefox :)

No fast On\Off access.

As user friendly as the addon seems, it ran slow and made the audio sound distorted (in my case at least). I wouldn't use this for bass boosting any audio or music.

Excellent, it works great!

Broke audio playback on bandcamp.com

html5 video do not play with AE

Seems too work pretty well! There's a few minor issues, such as preamp barely doing anything and no option to enable/disable limiting, but still a great add-on!

So no one has noticed yet that 64hz and 16K don't do anything? Hmmmmm
I added to my macbook pro as well as my Home imac and neither one works properly.
I guess the rest works as it should. Also a "Bypass" button would be useful so you could
compare with and without the settings you just tweaked. Mediocre EQ at best. better than
nothing though.

The best!!!It's working great even on Firefox Nightly.

Excellent, really awesome it works great!
