About this extension

Have you ever had that issue where a volume booster add-on would just forget what volume did you set it to on a page, or would outright mute some pages? No? Well, I have, and it's quite frustrating. That's why I created this add-on.

This is a simple free & open-source add-on that allows you to boost the volume of any* page and will (thankfully) remember the volume you set it to.

*Its only (known) limitation is that it can't boost the volume of webpages which play DRM-protected content using JavaScript, such as Netflix and Spotify.

For information about how to use the extension and technical details, read the README.md file on its GitHub page

Developer comments

From v1.8.0, I made it possible to use the extension without necessarily enabling the "Access your data for all websites" permission. It is, however, very encouraged to enable it, as it makes boosting audio less troublesome.
