Whilst I recommend that you use the plugins that are on the add-on stores of the respective browsers, building the apps yourself is perfectly possible, and __should__ be self contained within this application. I am building this on Ubuntu 15.04, but your luck may vary on other platforms.
If you want to modify the code in any way, you must run `npm run develop`. This build all the code, but doesnt delete any files you may have modified as `npm run build` does.
As you can tell, the quality of the code isnt perfect, or to a particular standard. Once the plugin works properly to a basic level, I will install some linting software to make the code look nicer, and possibly run smoother too.
All the time the app has a version of '0.0.0', the extensions are considered to be unstable and unlikely to work properly if at all.
