HTTPS-Everywhere<\/a> was a vital Browser-Extension<\/a> designed to provide automatic Encryption<\/a> for web traffic. It was developed as a collaborative project between the Electronic-Frontier-Foundation<\/a> and The-Tor-Project<\/a> to address the security vulnerabilities of the plaintext HTTP<\/a> protocol. By using a sophisticated library of rules, the extension would automatically rewrite requests to use the secure HTTPS<\/a> protocol whenever a website supported it, even if the user didn't explicitly request the secure version.<\/p> During its peak, HTTPS-Everywhere<\/a> was an essential tool for protecting users against man-in-the-middle attacks and eavesdropping. As detailed on the EFF Project Page<\/a>, the extension helped popularize the use of SSL-TLS<\/a> across the internet. It played a significant role in the broader Encrypted-Web<\/a> movement, which sought to make encryption the default standard for all internet communication.<\/p> However, as the web evolved, major Web-Browsers<\/a> such as Google-Chrome<\/a>, Mozilla-Firefox<\/a>, and Apple-Safari<\/a> began to incorporate native \"HTTPS-Only\" modes. This progress, combined with the rise of HSTS<\/a> (HTTP Strict Transport Security) and the availability of free certificates from Lets-Encrypt<\/a>, led the EFF<\/a> to retire the extension in 2022. The transition and the reasons for its sunsetting are documented in the EFF Technical Blog<\/a>. Today, the core functionality of HTTPS-Everywhere<\/a> is a standard feature in almost all modern browsing software.<\/p>
