Tool in the Spotlight: HTTPS Everywhere, a Firefox extension by the good folks at the Electronic Frontier Foundation (EFF) that encrypts your communications with many major websites, making your browsing more secure. It checks whether websites you visit offer encrypted browsing and if they do, automatically switches you to the encrypted version of the website.
