Cliget is a Firefox add-on designed for developers and IT professionals, enabling seamless downloading of login-protected files directly from the command line. It utilizes tools like curl, wget, or aria2 to generate commands that replicate browser requests, including sending cookies, user agent strings, and referrers. This functionality allows users to effortlessly download email attachments, purchased software, and source code from private repositories to remote servers without requiring local downloads.

This subscription-based tool is particularly beneficial for those who frequently handle web development tasks, as it simplifies the process of managing files from secured sites. Users should note the importance of security and privacy, as the add-on exposes cookies in the download command. For Windows users, enabling the "Escape with double-quotes" option is recommended to avoid compatibility issues.
