[HTTPS Everywhere](https://www.eff.org/https-everywhere) is a Firefox extension
included in <span class="application">Tor Browser</span>. It is produced as a collaboration between [The Tor
Project](https://torproject.org/) and the [Electronic Frontier
Foundation](https://eff.org/). 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 example, they might 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.
