I liked this initially, it worked well as an equalizer. Unfortunately it made YouTube music run like a dog so had to disable it

Did not save the preset. After closing the equalizer window and opening again all changes where gone, no saved preset was available.

Changing EQ settings and turning the EQ off/on did not result in any sound changes.

I tried it on Bitchute.
FF Version 101.0.1
OS: Kubuntu 22.04, Kernel 5.15.0-33

Все працює супер! Тепер YouTube Music на динаміках монітора грає краще :)

Works as expected!

Breaks some sites

Good as an equalizer, but it breaks some websites!

I'm sure many people won't realize this is the reason some videos/music don't play on websites like bandcamp or edpuzzle. I definitely didn't until I went through every extension I had, disabling and testing which one caused it.

It works perfectly! I totally recommend this exact equalizer! <3

Works very well but I wish it allowed to boost above 12db. I like to keep the preamp and volume low but I like that deep bass rumble while I'm working. Since it doesn't allow boosting above +12dB, I have to raise the volume a bit which distracts me while I'm working. Maybe the developer can add a pro mode with a warning that allows to boost above +12dB maybe upto 16-20dB atleast.

perfect, i can do anything i want

Good. But it breaks video playback on a number of sites so had to disable it.
