Now that we know how to enable the AppleScript menubar item, it's time to give Safari some AppleScript-enabled privacy features.
For all those times when you need to enable Private Browsing and 'private downloading' in Safari, a macosxhints reader has posted an AppleScript with setup instructions that can enable Private Browsing and mount a disk image and temporarily changing Safari's download folder to said disk image for the ultimate in browsing privacy (macosxhints uses 'online banking' as a usage scenario; I guess that works).
The script requires a little bit of setup and customization however, so check out the post for instructions. When you're finished you'll have a simple, handy AppleScript that prompts you to enable or disable Private Browsing in Safari, and then it will mount your encrypted (password-prompted) disk image for safe, secure and private downloading as well. Enjoy.
