What JavaScript means

JavaScript is on by default in every major browser. It’s usually turned off by a privacy setting, a script-blocking extension (NoScript, uBlock in advanced mode) or a site-specific rule.

What you'll see

  • “Please enable JavaScript to continue”.
  • Buttons, menus or forms don't work.
  • Blank pages on modern sites.

Why JavaScript happens

  • JavaScript disabled in settings.
  • Site-specific block or script-blocking extension.

How to fix it

  1. Chrome (desktop and Android)Open chrome://settings/content/javascript (Android: ⋮ → Settings → Site settings → JavaScript) and allow it; remove the site from Not allowed.
  2. Edgeedge://settings/content/javascript → turn on Allowed.
  3. FirefoxOpen about:config, search javascript.enabled and set it to true.
  4. SafariMac: Safari → Settings → Security → tick Enable JavaScript. iPhone: Settings → Apps → Safari → Advanced → turn on JavaScript.
  5. Check extensionsAllow scripts for the site in NoScript/uBlock or disable the extension to test.
How to tell it worked: The site loads its interactive features without the warning.

Stop it happening again

Use per-site script blocking rather than disabling JavaScript globally.
