WebSerial for Firefox

WebSerial API Polyfill for Mozilla Firefox browser

Introduction

This add-on allows to use the WebSerial API in Firefox.

It uses a native application to communicate with serial ports.

NOTE: Currently, the add-on only works on Windows and Linux (x86-64).

Installation

The add-on is available for download from Mozilla Addons: WebSerial for Firefox.

The native application needs to be installed on the computer first. The GUI will offer to download the native application when you first try to open a serial port.

Installation on Windows

The .exe file is an installer - just open it and install the native application.

Installation on Linux

Run script:

curl -s -L https://raw.githubusercontent.com/kuba2k2/firefox-webserial/master/native/install/linux_x86_64.sh | bash

or install manually

Put the downloaded file in ~/.mozilla/native-messaging-hosts
Rename it to just firefox-webserial.
Make it executable: chmod +x ~/.mozilla/native-messaging-hosts/firefox-webserial.

Create a file named io.github.kuba2k2.webserial.json in the same directory, with this content:

{
	"name": "io.github.kuba2k2.webserial",
	"description": "WebSerial for Firefox",
	"path": "/home/USER/.mozilla/native-messaging-hosts/firefox-webserial",
	"type": "stdio",
	"allowed_extensions": ["[email protected]"]
}

Adjust /home/USER to match your username.

Restart the browser and use the extension.

NOTE: On Alpine Linux (or other musl-based distros) you will need to have gcompat installed.

Usage

Some applications that can work on Firefox with this add-on:

Debugging

To view logs produced by the extension for debugging purposes:

Open about:debugging, click This Firefox
Find WebSerial for Firefox, click Inspect
Type in the console: window.wsdebug = true
Go to a website of choice, try connecting to a serial port - the console should show extension logs.
