About Safest Volume Booster
📢 Safest Volume Booster Chrome Extension
Safest Volume Booster is a lightweight Chrome extension that allows you to boost the volume of HTML5 video elements beyond the default 100%, using the Web Audio API.
Most importantly, this has as little permissions as possible.
Why I Made This
I had a volume booster extention for years via the Chrome App Store. There is a large issue with extentions getting hijacked and malicious code being uploaded. Due to extentions auto-updating, a malicious actor uploaded an update to it and got access to all my sessions. My bank session, my work sessions, etc.
✅ Why This Extension Is Safe
This extension uses minimal, privacy-friendly permissions:
Permission Purpose
activeTab Only runs on the currently open tab when you interact with it
scripting Injects volume boost logic — only on demand
storage (optional) Stores your preferred volume boost level locally
🚫 No access to:
Background scripts that run silently
All URLs or tabs in your browser
Any cookies, sessions, or page content unless you activate it
Why you have to click the extention for it to apply
I didn't want to run anything in the background. It only has the ability to run any code when it is clicked on.
👀 Notes
Works on most video players using <video> tags
Some sites (like Netflix or YouTube) may restrict audio routing due to strict CSP (Content Security Policy)
You may need to press Play once for the volume boost to take effect
