About Volume Control
Volume Control is a volume booster for Firefox and Chromium browsers, and the open source option in this list. Instead of a fixed percentage, it changes the gain from minus 32 to plus 32 decibels, so it can turn down a loud video as well as lift a quiet one. It started as another developer's project and is now maintained by Chaython, who publishes the code on GitHub.
It keeps settings per site, remembering volume, mute and mono for each domain, and lets you exclude sites or paths. A normalising mode can level loudness automatically, and keyboard shortcuts nudge the volume without opening the popup. The project's notes say Firefox can sometimes process DRM-protected audio, while Chrome and Edge cannot, so there only turning the volume down works.
The trade-offs are people and polish. One developer maintains it, the Firefox rating is 3.8 from about 200 ratings and the Edge listing has few users, so it has less track record than Volume Master. It asks for access to all sites, which the listing says is for finding media, and states there is no analytics or telemetry. Pick it if you are on Firefox, where we found no Volume Master listing, and go gently with the sliders.

It can read and change data on all websites and use the active tab. It needs this to route the audio of any page through its volume control.
