Firefox Send lets you share files with end-to-end encryption and a link that automatically expires, so you can keep what you share private and ensure it doesn’t stay online forever. Firefox Send makes it simple to share large file sizes – perfect for sharing professional design files or collaborating on a presentation with co-workers. With Send you can share file sizes up to 1GB quickly. You can set the expiry based on the number of times the file is downloaded or the number of days from the date of sending; or select a secret password and share it with the recipient only, for added security. Just select a file to upload and get (copy) a link which can be shared. You can share to any device and your recipient can be on any platform. Sign up for a free Firefox account to send files up to 2.5GB.
