Mozilla has publicly launched its Firefox Send file-sharing service after a lengthy testing period. It allows you to send files via a link to anyone and set conditions for access like a time period or number of downloads before the file expires.

Firefox Send can handle files as large as 2.5GB. When the Test Pilot period for the service began in August of 2017, the limit was 1GB; that limit still applies until you sign in with your Firefox account (opening an account is free).

You can set a limit to how many times the file can be downloaded before it is deleted from the servers: one, two, three, four, five, 20, 50, or 100 times. You can also set a time limit before deletion—seven days, one day, one hour, or five minutes. Finally, you can set a password of your choice for access to the file. After you go through this brief process, you’ll get a link to send to the recipient to download the file.
