Many sites that support secure transmission via HTTPS, still don’t offer encryption as a default, or sometimes they combine pages with both secure and insecure items. HTTPS Everywhere, a new Firefox plugin, makes it easier for Firefox users to always use the secure version of a number of popular sites. This is useful for those surfing in public hotspots, where an insecure site (using HTTP vs HTTPS) is visible to sniffers. The free plugin currently works for Facebook, Twitter, Paypal, Google Search and half a dozen other popular sites.
