rsstodolist is a service to build RSS feed, hosted on Google App Engine, at https://rsstodolist.appspot.com. You can deploy the server code on your own server (https://github.com/paulgreg/rsstodolist-server) to host your private instance.
This is the rsstodolist add-on for Firefox, allowing to add URL to a RSS feed, available on the Mozilla Add-on repository.
First, you need to install the Firefox SDK Add-on via a npm install jpm.
To run the addon, type ./node_modules/.bin/jpm run and ./node_modules/.bin/jpm xpi to build the package.
