Features & Capabilities

Two tools in one small popup: a volume booster and a playback speed controller.

Some videos are just too quiet — laptop speakers maxed out and you still can't hear the dialogue. Others you'd rather watch at 1.5x. This does both from a single 220px popup, so you're not juggling two separate extensions.

FEATURES

• Volume boost from 0% to 600%, using the Web Audio API • Playback speed from 0.25x to 4x • Quick presets for the settings you actually use (100/200/400%, 1x/1.5x/2x) • Collapsible panel — tuck it away when you only need one control • Your settings are remembered between sessions • Works on any site with HTML5 video or audio

PRIVACY

No ads. No tracking. No analytics. No account. Nothing leaves your browser — your volume and speed preferences are stored locally on your own device and nowhere else.

PERMISSIONS, AND WHY

• Storage — remembers your volume, speed and panel state between sessions • Access to website data — required to reach the video or audio player on whichever page you're watching. Nothing is read from the page or sent anywhere.

NOTES

Volume above 100% is achieved by routing audio through a Web Audio gain node. On a small number of sites the media is served without the CORS headers this requires; on those, volume is limited to the normal 100%. Speed control still works everywhere.

Very high boost levels can distort audio on some speakers. Start around 200% and increase from there.

Free and always will be. If it saved you some hassle, there's a tip button in the popup — entirely optional.

User Reviews

Fixes a problem I've been having in Firefox with audio being too low despite cranking everything to the max. Great little extension.

Is 1 Speed & Volume Booster Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

1 Speed & Volume Booster requires a few sensitive permissions. Exercise caution before installing.

Risk impact analysis details

Critical Allows access to all websites, posing a significant security risk as it can monitor and modify data from any visited site.

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

1 Speed & Volume Booster is recently added, and hasn't been around long enough for us to gather enough data to accurately assess its risk level.
