The idea is to create a WebExtension that allows one to become a Snowflake bridge by just installing it. That way it only suffices to install an extension and forget about it, unlike the approach of keeping a tab always open with the snowflake JS code.

Since it's based on WebExtensions it can be easily deployed for other browsers in their addon store.

I did try to make one myself but I don't have the expertise and time to debug all the problems that resulted. One of the important take aways that I learned in that process was that automatically loading scripts from external sites is prohibited and will result in the addon not passing the review in the addon store, so the snowflake.js and modernizr.js should be embedded with the addon. However, this would require modifying snowflake.js since when it's loaded locally it throws some typeError and doesn't show that there's some connection to snowflake.bamsoftware.com in the browser console. For debugging, to verify that the addon works as intended one may load it from about:debug and check about:networking in the DNS and WebSockets part.

For the implementation these resources should be loaded in the background to ensure a permanent state with this in the manifest.json,

"background": {
                "page": "pages/Snowflake.html"
        },
