Mozilla is one company that really respects the freedom of internet users. While its browser rival Google Chrome ttys to track users and recommend advertisements and search results that suits them, Mozilla’s firefox tries to respect ones privacy if one wishes to be so.
For long we have this single sin on, that is each website needs to authenticate user, and it has to make user under go painful task of creating an login account. This process is eased by stuff like openId, Google, Facebook and Twitter’s sine sign on process. But Google and Facebook track a lot of ones behavior since their business is based on advertisement revenues, which depend on these websites knowing what exactly the user wants, and hence tracking is inevitable and your privacy i compromised.
Mozilla is a non profit company that runs on ones donations and it has put up a single sign on framework called persona https://developer.mozilla.org/en-US/docs/Mozilla/Persona . Persona does not track a person, compromise ones security and possibly won’t collaborate with NSA.
So try using it in your website. Any gem for it anyone? It would be nice to to have a compact gem to us it in ones web applications. hopefully it catches up and leads.
