GNU LibreJS, or simply LibreJS, is a free software web browser extension for Mozilla Firefox-based browsers, written by the GNU Project. Its purpose is to block nonfree nontrivial JavaScript programs and allow free or trivial JS in a user's web browser. The add-on was written to address the so-called "JavaScript Trap" first described by Richard Stallman in 2009, a situation in which many users unknowingly run proprietary software in their web browsers.

The add-on was written to address the so-called "JavaScript Trap" first described by Richard Stallman in 2009, a situation in which many users unknowingly run proprietary software in their web browsers. ==Reception== Klint Finley of Wired, after going without JavaScript for a week, wrote, "The Free Software Foundation launched its Free JavaScript campaign in 2013 to promote websites using only free and open source JavaScript code, or making sites function without it. To help users avoid running proprietary JavaScript, they developed LibreJS, a plugin for the Firefox web browser that blocks most, but not all, JavaScript from running. They also work with engineers to help reduce dependence on proprietary JavaScript." However, the FSF does not use the term "open source" and actively advocates against using it, preferring the term "free software" instead. Cory Doctorow of BoingBoing, discussing Finley's article, said he had used NoScript for years, and got around the problems Finley identified by whitelisting pages with wanted functionality that only works with JavaScript. Websites have been criticized or rated based on whether they work without JavaScript or with LibreJS enabled. ==References==
