Have to disable on some sites like viki.com
This is really annoying.2 years without update. Is this addon abandoned?
Still 5 stars but would be nice if this could be fixed.

Finally my headphones received some kick. High5! Hoping for 4,5,6,8 channels (upmix is fine) for firefox. Keep it up! Best regards!

Das ist sehr gut! Perfect! Каращо! )

This is just what I needed. Higher pitched tones really disturb me. Thank you very much \(0.0)/

Guter Klang und leichte Einstellungen

Just about perfect

l'extention équalizer est super pratique, on peut tout gérer le top!

It's not a bad little audio tool. I like the pre-sets.

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 :)
