The foundation Mozilla is developing a new version of Firefox beta (version 39), which will primarily enable you to invite others to Firefox Hello chats using social networks.
The update is already available for Mac, Windows, Android and Linux.
By sharing Firefox Hello, you can link your Facebook, Twitter, or LinkedIn account.
Firefox 39 for Android, specifically allows users to paste content into the clipboard as editable content.
Additionally, the Project Silk brings better animation and scroll on OS X devices, as well as Safe Browsing with malware protection.
