To use NativeExt, you must download and install its desktop application as well. The extensions option page on about:addons will guide you through the process.


NativeExt doesn't do anything on its own. It is a special module that extends the capabilities of other browser extensions. It allows extensions that were explicitly allowed by the user to execute node.js JavaScript code on the computer, with the full access of the current user account. While this is, from a security perspective, generally equivalent to installing a program on the computer, it is much easier to install and update for the user (once initially set up, allowing an extension requires only a single click, and updates are implicitly included with the extension itself) and easier to develop and maintain for the developers (write/bundle standard node.js modules and ship them with the extension; no platform specific installation or update code required).

For more information on what and why NativeExt is, see the project homepage.

User reviews
It seems to be sheer impossible to install this extension: Messages are displayed for mere seconds, rendering them impossible to read and the setup instructions are impossible to understand, at least by me with 30 odd years in IT under my belt. Why it has to be this difficult is beyond me. I'd give it zero stars if I could. Highly frustrating!
