Unsplash How Firefox Send Works To use Firefox Send, you'll need to sign up for a Firefox account, which is the same account you use with Firefox Sync. Firefox Send is often a better choice than email because of its ability to handle larger file sizes as well as its security features. Sign in to your Firefox account. Select your profile icon, then select Firefox Send. Select the expiration condition (either after the file has been downloaded a certain amount of time or a period of time has passed). Select Protect with password (optional). If you protect the file with a password, type a password in the Password field. Once the file has been uploaded, you'll be presented with a share link. Select Copy link, and then paste the link into an email or message to your recipients. You'll automatically be returned to the upload page, where your current upload will be listed. From this view, either view the details of your download, select Copy Link to send the link again, or delete the download from the Firefox Send server.
