The full version of Firefox Send, which does not require Firefox to use, has the same 1GB file size limit as its predecessor for unregistered users accessing the service anonymously; those willing to register for a free Firefox account, meanwhile, have this limit increased to 2.5GB. Firefox Send is now out of testing and boasts a magnified 2.5GB file-size limit if you log into Firefox account. Mozilla has been working on a free tool called "Firefox Send" for some time now, and it should help to alleviate the situation when required.
Users can set files to expire after a certain period of time, or after a certain number of downloads.
Files that are sent using Send are end-to-end encrypted which means your data is secure from the moment you send it to the moment it's opened. For those seeking extra privacy, shared files can also be locked with a passphrase.

"By default, files are stored for a maximum of either 24 hours or 7 days". Firefox Send features end-to-end encryption, enabling users to send sensitive documents they may otherwise be uncomfortable uploading, such as financial papers or business reports.
Why it matters: Sending large files to others can be a tricky process sometimes. The service has been built and promoted by the Mozilla Foundation, the non-profit behind the popular browser and several other initiatives that make the web a better place for everyone. "As with all Firefox apps and services, Send is Private By Design, meaning all of your files are protected and we stand by our mission to handle your data privately and securely".
