суууупер, все работает

It works and it's cool but not powerful enough

Made every video crash and show:
No video with supported format and MIME type found
At first I thought that this is cause of lack of codecs in the system, but after checking stuff up and disabling this addon everything worked normally.

ломает вывод звука

echoed audio since extension installed. bug gone after uninstalling this extension

good choise

I like it but I really want to be able to adjust ONE tab and leave the rest alone. Because I always forget to turn it off >.<

I use this almost exclusively on YT video, and it works amazingly. I listen to a lot of music on YT video (versus it's actual music service due to a 1.25 speed preference potential autism) and I love this extension on Firefox, while wearing full noise-cancelling headphones.

Click your puzzle piece, open the mixer, and try all of the audio presets on your favorite banger. Strangely, the 'Ska' preset seems the fullest, but I love toggling the 'Live' and 'Club' settings.
There is a lot to play with, and the differences in audio are so stark. Try 'Classical' on the most un-classical song ever, or try "Live' on Daft Punk. It's fun, new, and free, you free-loading complainer.

Of course you can tweak it further with the sliders, I am not well versed in the audio tech, but for a lite add-on, I couldn't be happier.

Работает, не идеально, но хотя бы так, это единственное рабочее расширение Эквалайзер для FF, надо только добавить Preamp

1. Makes all < video > elements with mp4 sources have MIME errors
2. When the video is able to play, 70% of the extension isn't functional doesn't work
3. But when it does work it is kinda nice

Works ok but breaks videogifs.

It's not working in the latest Firefox update.

Tuyệt vời

Work in multiple sites

It greatly enhances listening experience. Presets are pretty close by genre, only requiring minor adjustments from son to song.

Good but does not allow videos to play in youtube studio when showing analytics.

the equalizer works... the audio sounds better. great !

Super wonderful! Twailer

Complete trash, it does nothing. Says it has preset BUT WHERE ARE THEY??? Morons.

Please fix it, its the only audio extention i can easily add a little bass quickly when i listen to music but having to diable it entirely whenever i dont specifically use it for youtube due to the fact that it breaks so many websites with media makes it not worth using.
