The developers behind the Mozilla Firefox are busy testing few number of latest tools and features a popular open source browser.
These tools and features include Send, which is a free cross-browser web app for transfer of self-destructing files of size up to 1GB.
Only you need is to point any latest browser to this page and drop any file on there. After that, you can be able to transfer or share files by sending them a link.
As from Mozilla’s point of view, it is fully private and encrypted on the client side, which shows that the particular organization will not be able to see the contents of the client, and the provided link will only work for a single download or 24 hours, whichever comes sooner.
Send operates as displayed with uploads as quick as other choices including WeTransfer and I think it is a great choice for you whenever you need to share file privately and securely without bothering about the access of any outsider.
