Works well - when it works. Can reduce frequencies to improve spoken word audio on bad speakers, but does not work with some websites (Discord) and seems to lose the audio device sometimes.

Great little add-on, works flawlessly. Highly recommended!

Does nothing

Best equilizer for Firefox, but BUGGY! Sometimes no sound, sometimes no video or sound with error "NO VIDEO WITH SUPPORTED FORMAT AND MIME TYPE FOUND" in latter case. (View release notes page on Firefox download page to reproduce). Remedy via right-click whitelist mode, but excruciatingly annoying! Applicable to all Firefox versions, past through latest. Please fix!

This things presets suck... Also there are issues with memory, videos, and sound after prolonged use. Videos would occasionally not load.. then the worst thing happens of it sounding like it is overlapping the audio track on top of itself, slightly offset. Like numerous copies just a second or two different from where they play the same noise as their other copies. It's like the best thing to listen to... it's like watching those old channels you weren't allowed to get on wired cable. Occasionally you see a boob, but was it worth the hours?

Works as intended. Was frying my brain trying to equalize audio in Windows, even though I have a Behringer sound card. Then I remembered there could be a specific app EQ, and found this. Worked imediatelly. My monitor speakers are way to bassy, so this solved the issue . 🙏

When using this extension, an error appears on some videos 'No video with supported format and MIME type found'

This extension somehow breaks Visa 3D Security popup, it just loads infinitely without proceeding. I've spent an hour trying to pinpoint the extension that causes that. IT'S THE EQ, WHY THE HECK DOES IT BREAK ONLINE PAYMENTS. I can't even. Ugh.

Does not work

It seems to be good, and then you turn it off, and everything sounds worse. So you think to yourself, "Huh, it must be doing something" - Then you disable the add-in, and everything sounds the same as when it is turned on.

I genuinely cannot tell if this actually improves audio quality or not. Add to it that this actually breaks video functionality on a numerator of different sites that host video content (No, YouTube is not one) - And the downsides of this plugin outweigh the (maybe) benefits.

крутая штука для браузера

Used to work but now does nothing. Latest version of firefox. Uninstalled and reinstalled multiple times. Sorry bro it's broken

very janky, sometimes breaks completely and only reinstalling fixes it, sometimes the on/off button doesn't work and you have to adjust a slider for the equalizer to start working, but otherwise its ok i guess
