I wrote about the original test version of the free Mozilla Firefox Send service in July 2018.
Mozilla Firefox Send is a free service open to any user, accessible with any browser, that allows you to securely send a large (up to 2.5GB) file to another internet user. The process is very simple, you upload a file, they provide a unique link that you share with the intended recipient.
The file can be expired after one to one hundred downloads or 1 to 7 days.
You can also protect the file with a download password
There are other services but most charge for add on features like download password protection or expiry configuration. Firefox Send is completely free and comes from the fine folks over at Mozilla that we trust.
