  1. Like other web browsers, Firefox enables JavaScript by default. You won't need to enable it if you haven't disabled it. [5]
    • If you're using Firefox on your Android, iPhone, or iPad, there is no way to enable or disable Firefox–JavaScript is turned on by default and cannot be disabled.
  2. If you don't see this option, just skip to the next step.
  3. This filters the settings on the page to display the one you need.
    • If you see "true" next to "javascript.enabled," JavaScript is already turned on and you don't need to enable it.
  4. If you see "false" next to "javascript.enabled," click the button with two arrows on the right side of the menu item to toggle JavaScript back on.
    • If you're still getting JavaScript errors in Firefox, disable any third-party privacy plugins that could be blocking JavaScript. Some of the more popular JavaScript-blocking extensions include "NoScript", "Ghostery," and "Script Blocker Ultimate." [6]
    • If all else fails, uninstall and reinstall Firefox to restore all of the default settings. Because JavaScript is a foundation of the Firefox browser, reinstalling should restore its functionality.
