Mozilla today announced the formal launch of Firefox Send, a file-sharing service that got its start as one of the organization's "Test Pilot" experiments. Along with its graduation from an experiment, Firefox Send has also picked up some enhancements to upload limits and control over what you send.
Firefox Send acts as a secure file-transfer service, intended to help you privately share sensitive files with others. Available through any browser at send.firefox.com, Firefox Send allows you to upload files and send them to someone else with end-to-end encryption. It also gives you control over how the files are treated, allowing you to set the file link to expire, limit the number of downloads, and set a password for the recipient to enter before being allowed to download the files you share.
At its most basic, Firefox Send allows you to share files up to 1GB in size. If you sign up for a Firefox account, that limit expands to 2.5GB. Crucially, recipients don't need a Firefox account to download files that you share; all they need is the link and, if set, a password.
