For those of you worried about web browsing security, you might want to use Firefox and this HTTPS Firefox add-on which automatically switches your browser to HTTPS whenever it’s detected.
I think this is a great idea, especially for any sites that need a login and they usually provide HTTPS versions.
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 rewriting all requests to these sites to HTTPS.
