When a quiet podcast or a soft YouTube mix leaves you leaning toward your laptop, Loudly - Audio Amplifier, developed by POLPROG, gives you browser-level control to push web audio past the usual ceiling. The extension supplies volume and speed controls accessible from a compact popup, letting you tweak playback without leaving the active tab. It targets commuters, remote-meeting attendees, and people with low speaker output who need quick, per-tab media adjustments.

What is Loudly used for?

You use this Firefox extension when site audio is too quiet or poorly mixed, for example quiet podcasts, soft YouTube uploads, or low-volume participants in video calls. The tool operates inside the browser to change how a single tab plays back media, giving you direct control over tab audio rather than the whole system. That focus keeps the control scoped and immediate when you need it.

What audio elements and speed controls does it handle?

Loudly works with all HTML5 audio and video elements, so streaming pages and embedded players respond to its controls. The built-in speed slider covers 0.25x to 4.0x playback, letting you slow lectures or speed through long recordings. The extension is provided for Firefox and lists compatibility beginning with recent browser builds, so you control HTML5 media inside the browser environment.

How does the interface fit into daily browsing?

The extension uses a lightweight popup for adjustments, so you change settings without leaving the page. The package is compact, roughly 51 KB, and the popup exposes core controls for quick access. That design means you can raise volume or alter speed during playback in a few clicks, which suits short, on-the-fly fixes rather than a prolonged editing session.

How loud can it get and what are the limits?

Loudly applies amplification up to 500% using a GainNode implemented through the Web Audio API, which is a technical approach that yields cleaner amplification compared with ad-hoc tricks. Higher boost levels can produce audible distortion or place strain on small laptop speakers, so you should increase gain cautiously and monitor sound quality on your device.

A practical gateway for louder tab audio with preserved privacy

If you need straightforward, tab-focused audio control inside Firefox, Loudly is a practical entry point that stores per-site preferences and keeps all settings locally, with no external tracking. The extension’s local storage of site settings and the developer’s privacy emphasis make it appropriate for privacy-minded users who want quick fixes during streams or calls. Expect browser-scoped behavior rather than system-wide audio management.
