HTTPS Everywhere is produced as a collaboration between The Tor Project and the Electronic Frontier Foundation. 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. The HTTPS Everywhere extension fixes these problems by using clever technology to rewrite requests to these sites to HTTPS. Information about how to access the project's Git repository and get involved in development is here.

Webmasters and prospective contributors: Check the HTTPS Everywhere Atlas to quickly see how existing HTTPS Everywhere rules affect sites you care about! HTTPS Everywhere is governed by EFF's Privacy Policy for Software.

Problems Installing: Some people report that installing HTTPS Everywhere gives them the error: "The addon could not be downloaded because of a connection failure on www.eff.org." See this FAQ entry for help.
