Thanks to Mozilla letting an intermediate signing certificate expire, the Tor community was thrown into disarray over the weekend when the NoScript security add-on was suddenly killed for both Firefox and the Tor browser. A fix is available for Firefox, but the Tor issue continues.
NoScript is a Java-blocker that prevents active content from running if it’s from untrusted sites, and it protects users against cross-site scripting (XSS) and other web security exploits. It’s officially trusted by Mozilla and Tor, but it’s also used in other browsers.
