<span class="application">[Tor Browser](https://www.torproject.org)</span>is a web browser based on [Mozilla Firefox](https://www.mozilla.org/firefox/) but configured to protect your privacy.
Notice the padlock icon on the left of the address bar saying "mail.riseup.net".Notice also the address beginning with "https://" (instead of "http://"). These are the indicators that an encrypted connection using [[!wikipedia HTTPS]] is being used.
[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.
