<span class="application">[TorBrowser](https://www.torproject.org)</span>is a web browser based on [Mozilla Firefox](https://www.mozilla.org/firefox/) but configured to protect your privacy.
Using HTTPS instead of HTTP encrypts your communications with the website and prevents the [[Tor exit node from intercepting your communications|about/warnings/tor#exit]].
For example, here is how the browser looks when we try to log in to an email account at [riseup.net](https://riseup.net/), using their [webmail interface](https://mail.riseup.net/):
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.
When you are sending or retrieving sensitive information (like passwords), you should try to only use services providing HTTPS. Otherwise, it is very easy for an eavesdropper to steal whatever information you are sending, or to modify the content of a page on its way to your browser.
