“HTTPS Everywhere is a Firefox extension produced as a
collaboration between The Tor Project and the Electronic Frontier
Foundation. It encrypts your communications with a number of major
websites.“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.”
