Mozilla has announced Firefox Send is now available for use as a free file transfer service with built-in end-to-end encryption. Send allows users to safely and simply share files from any browser without having to worry about their private information existing in the cloud. Send will be available as an Android app in beta later this week. Users can set when their file link expires, the number of downloads, and whether to add an optional password for an extra layer of security. Send allows for fast file transfers of up to 1GB with an option to transfer 2.5GB if users sign up for a free Firefox account. Recipients only have to click a link to download the file.
