There are plenty of options for sending large files from one point to another. You can always use Dropbox, Ge.tt, WeTransfer or even pCloud Transfer, which work very well. But it never hurts to have an extra option, especially when it comes with Firefox's quality seal. That service is called Firefox Send and allows sending up to 2.5GB of files, including several security options.

Firefox Send: How to Send Large Files (Up to 2.5GB)

Like all similar services, file storage on Firefox Send is temporary. It's not suitable for hosting your files for a prolonged time (like MEGA or Dropbox, for example), but only for sending them from one point to another. Fortunately, you can set the rules for automatic file deletion yourself, with two categories: by number of downloads (from 1 to 100 downloads) or by time (from five minutes to seven days).

The service features end-to-end encryption, is completely free, works in any browser (regardless of brand) and doesn't require registration. However, if you want to send up to 2.5GB of information, have all 100 downloads or seven days of storage, you will need a Firefox account (also free). Sends without registration can't exceed 1GB, one download, and they'll be kept for only one day, which is still not bad.

Sending files with Firefox Send is simple and has end-to-end encryption.

Firefox Send is very simple to use, no fuss: just drag the file(s) you want to share, select the number of downloads after which they'll be deleted, the desired storage time, and set a password to protect the transfer if you want. Once that's done, the service will upload your files and give you a link to share. Anyone with that link, as long as the deletion rules haven't been met and they have the password if you set one, can download whatever you put in the package. That said, rapid, simple, free, and with Firefox's backing.
