Firefox Send with file encryption and password protection lets you send files (1GB to 2.5GB) safely and securely. When you upload a file, Firefox Send generates a link you can share with your recipient. You also have the option to set a password and change the expiration settings for extra security. Your files are not saved to the cloud -- they belong only to you.
