Ghostzilla

Ghostzilla is a dated web browser program for Windows that doesn’t exactly hide your typed addresses but it does make your web browsing session very inconspicuous as it stations itself inside an active program window. As you type web addresses on Ghostzilla (which uses the Mozilla browsing engine, hence the name), it loads websites in a transparent layer, and shows single images in black and white. Additional images will only surface if you hover your mouse over. Please note that even if you use Ghostzilla, your school or company will still be able to log websites you accessed.
