About this extension
WebSerial API Polyfill for Mozilla Firefox browser

This add-on allows to use the WebSerial API in Firefox. It uses a native application to communicate with serial ports (works on Windows and Linux).

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.

Read the installation guide on the project page: https://github.com/kuba2k2/firefox-webserial

The add-on is open source. All binaries are built with GitHub Actions:
