HTTP Nowhere is a browser extension to block unencrypted web traffic for added security. It adds a button to your toolbar that lets you disable all unencrypted web requests and only permit those you choose. When URLs are blocked, an indicator appears on the button and you can then choose to allow or ignore them in the future.
