When you use Send, Mozilla receives an encrypted copy of the file you upload, and basic information about the file, such as filename, file hash and file size. Mozilla does not have the ability to access the content of your encrypted file, and only keeps it for the time or number of downloads indicated.
在您使用 Send 时，Mozilla 会收到您上传的文件的已加密副本以及文件的基本信息，例如文件名、文件散列值和文件大小。Mozilla 无法访问加密文件的内容，并且只按所要求的时间或下载次数保留。
