Firefox Send has been discontinued as of September 17th, 2020. The reason to shutdown this service is some abusive users were beginning to use Firefox Send to ship malware and conduct phishing attacks. So Firefox team has shutdown it. For more details, see this link.

Nowadays, file sharing between Computers has become incredibly easy! A plethora of tools and private/public cloud services are available to share files locally or somewhere else via Internet. Today, we will see one such tool named Firefox Send. Firefox Send is actually an online file-sharing service that allows you to easily and securely share files over Internet. It allows us to send files up to 1 GB without sign-up . To send file sizes up to 2.5GB, you need to create a free Firefox account.

As you might have already guessed, it is developed by Mozilla and is freely available for all. Since Firefox Send is a web file sharing service, you can access it from anywhere from any Internet-enabled device, regardless of the operating system you use. You don't even need to use Firefox browser to use this service. Any web browser is sufficient!

Firefox Send encrypts the files with 128-bit AES-GCM encryption method. In addition, It offers a few more security options which allows you to:

  • Choose when your file link expires (after the number of downloads or days). For instance, you can set the file link should expire after 10 downloads or 10 days.
  • Set password to the files.

So the users can feel safe that their private and important data does not stored somewhere in the cloud.

Click the on the button that says "Select files to upload" and choose one or more files that you want to share. As I already mentioned, you can upload files up to 1 GB without signing up or 2 GB with sign-up. And then choose the security options. For example, I have chosen the link should be expired after 1 download or day. And also I set the password for the files.

To add additional files in the existing list, simply click on "Select files to upload" button again and choose the files from your local disk. Once done, hit the Upload button.

Hi OSTechnix. Sorry to say that Firefox Send has been decommissioned since 17th Sept 2020. The link to the reason is here: https://support.mozilla.org/en-US/kb/what-happened-firefox-send.
How unfortunate that there are people out there who would see every opportunity to misuse some good facility for their own sordid intentions. Hopefully Firefox will reinstate the Send facility with better security features. Neways, keep up the good work OSTechnix. I always refer to your website especially for any Linux info and knowledge. I am a newbie to Linux and your articles and blogs are really informative.
