WebHID Firefox

WebHID

By: Kazoku Add-on
Brings the WebHID API to Firefox: configure your keyboard, use your hardware wallet, or control your USB DAC from any website, via a fast local daemon.

Features & Capabilities

Firefox does not support the WebHID API out of the box, so this addon fills the gap. Install it plus a small background daemon, and WebHID websites work as if Firefox supported them natively. Configure your custom keyboard in a web-based configurator (VIA, Vial, and similar), sign transactions with your hardware wallet from a web app, control your USB DAC from its browser interface, or use any other HID device, all without leaving Firefox.

Requires a companion daemon to talk to your hardware. It is a small, open-source background service (Linux, macOS, and Windows supported). Download and setup instructions: https://github.com/K4zoku/FF-WebHID

Features

  • WebHID for Firefox: websites that already support WebHID work without changes.
  • Fast and smooth: built for demanding devices that send thousands of updates per second, without slowing down the page you are using.
  • Cross-platform: works on Linux, macOS, and Windows.
  • Self-healing: if the daemon restarts or a connection drops, everything reconnects automatically.
  • Hot-plug: plug devices in or unplug them any time; no page reload needed.
  • Per-site control: set up each website the way you want and change it any time, without reloading the page.
  • Device chooser your way: pick devices from a clean overlay, a popup in the address bar, or a separate window.
  • Private and secure: websites can only reach devices you explicitly choose, security keys and the system mouse and keyboard are always blocked, and all data stays on your machine.
Installation
  1. Install the addon from this page
  2. Install the system daemon (see the installation guide)
  3. Visit any WebHID-enabled website and start using your devices
Privacy
  • All device communication stays on 127.0.0.1 (localhost)
  • No data is sent to any external server
  • Connections to the daemon stay on your machine and are token-authenticated
  • Device permissions are stored locally per site origin

Is WebHID 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.

WebHID requires some sensitive permissions that could impact your browser and data security. 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.

WebHID is recently added, and hasn't been around long enough for us to gather enough data to accurately assess its risk level.
