Works well on Firefox 153.0.3(64 Bit).
Not found any sites that don't Function Netflix, Prime, Youtube, Now.
Simple and Effective.

Установил и забыл, а оно помогает каждый день

The actual functionality is completely fine, but I don't like the UI that much, the text is hard to read sometimes and the dark mode imo looks awful.

this works ok for youtube but it completely breaks (mutes) audio on other sites, like with Imgur especially. None of the files with audio will playback anymore, unless the file is saved and viewed elsewhere, or in a private session without this addon. Please fix this so mp4 audio is not muted?

Edit: thanks for working on a fix

easy installation, works perfectly :)

Does not work for Youtube.

Works but Crunchyroll blocks you from watching anything with this enabled.

You can just disable it temporarily, but it would be nice to see a fix.

Max Sound Booster Extension is a great tool for increasing audio volume beyond the default browser limit. It works smoothly for videos, music, and online meetings, delivering louder and clearer sound without complicated settings. The interface is simple and user-friendly, making it easy for anyone to use. It’s especially helpful when laptop or browser volume feels too low. Overall, a reliable and effective extension for improving your audio experience.

since the same website might have louder content (like youtube streams vs normal music content), new tabs should be able to use default volume regardless of previous website volume - the feature to remember website settings should be a option - this would make it a 5 star extension :)

Exactly the add-on I needed to boost the audio on my crappy earbuds. Thanks, Dev!

just great as it works fine, I can hear now )

This extension works all the time. I've used other sound boosters and they require you to reload when you start a new website. Chrome extensions are notorious for this and the extension does nothing. I appreciate the developers that created this extension. Highly recommend.

Super compared to other paid extensions.

I love this app.
