An anonymous reader writes: Mozilla today launched Firefox 44 for Windows, Mac, Linux, and Android. Notable additions to the browser include push notifications, the removal of RC4 encryption, and new powerful developer tools. Mozilla made three promises for push notifications: "1. To prevent cross-site correlations, every website receives a different, anonymous Web Push identifier for your browser. 2. To thwart eavesdropping, payloads are encrypted to a public / private keypair held only by your browser. 3. Firefox only connects to the Push Service if you have an active Web Push subscription. This could be to a website, or to a browser feature like Firefox Hello or Firefox Sync." Here are the full changelogs: Desktop and Android.
