Enforce your rules!

HTTPS Everywhere's official website. 

HTTPS Everywhere is a Chrome and Firefox add-on that enforce every website to connect through SSL connection (if available). As a result, it will provide a better and higher level of security for your web  browsing experience. However, in some cases, using a SSL connection cause a bit speed reduction, but the fact that your connection is fully encrypted and secured and no one can easily spy on you, steal your information or blackmail you, makes it worth.

HTTPS Everywhere is produced as a collaboration between The Tor Project and the Electronic Frontier Foundation. Many sites on the web offer some limited support for encryption over HTTPS, but make it difficult to use. For instance, they may default to unencrypted HTTP, or fill encrypted pages with links that go back to the unencrypted site. The HTTPS Everywhere extension fixes these problems by using a clever technology to rewrite requests to these sites to HTTPS.

Firefox version in now on version 3 stable. However Google Chrome's version is in alpha phase (but works fine). Unfortunately, HTTPS Everywhere dose not provided on Firefox Add-Ons official page and you should get it directly from Electronic Frontier Foundation website.
