Editing HTTPS (section)

===Browser integration===

Most [[Web browser|browsers]] display a warning if they receive an invalid certificate. Older browsers, when connecting to a site with an invalid certificate, would present the user with a [[dialog box]] asking whether they wanted to continue. Newer browsers display a warning across the entire window. Newer browsers also prominently display the site's security information in the [[address bar]]. [[Extended validation certificate]]s show the legal entity on the certificate information. Most browsers also display a warning to the user when visiting a site that contains a mixture of encrypted and unencrypted content. Additionally, many [[Content-control software|web filters]] return a security warning when visiting prohibited websites.

The [[Electronic Frontier Foundation]], opining that "In an ideal world, every web request could be defaulted to HTTPS", has provided an add-on called HTTPS Everywhere for [[Mozilla Firefox]], [[Google Chrome]], [[Chromium (web browser)|Chromium]], and [[Android (operating system)|Android]], which enables HTTPS by default for hundreds of frequently used websites.<ref>{{cite web |first=Peter |last=Eckersley |url=https://www.eff.org/deeplinks/2010/06/encrypt-web-https-everywhere-firefox-extension |title=Encrypt the Web with the HTTPS Everywhere Firefox Extension |work=EFF blog |date=17 June 2010 |access-date=20 October 2018 |archive-url=https://web.archive.org/web/20181125102636/https://www.eff.org/deeplinks/2010/06/encrypt-web-https-everywhere-firefox-extension |archive-date=25 November 2018 |url-status=live }}</ref><ref>{{cite web |url=https://www.eff.org/https-everywhere |title=HTTPS Everywhere. |work=EFF projects |access-date=20 October 2018 |archive-url=https://web.archive.org/web/20110605022218/https://www.eff.org/https-everywhere |archive-date=5 June 2011 |url-status=live |date=7 October 2011 }}</ref>
