bash-completion vs BufferZone

bash-completion is a shell script that enables tab completion functionality in the bash shell for a large number of shell commands and applications. It makes using the command line faster and more convenient.

BufferZone is a free firewall program that protects your computer from malware, hackers, and internet threats. It works by isolating your web browser and email client into a virtual container, preventing threats from accessing the rest of your computer if you happen to visit an infected website or open a malicious email attachment.
