F.A.Q

Why do I need JavaScript enabled on Mozilla Firefox?

JavaScript is a popular programming language that's essential for modern websites to function correctly on Mozilla Firefox. It powers most of the dynamic features you see on web pages, including button clicks, navigations, and form submissions. Enabling JavaScript in your Firefox browser is an easy process. In fact, it should only take you only a minute or so to complete.

How do I know if JavaScript is working on Mozilla Firefox?

On Mozilla Firefox, JavaScript is enabled by default, but you can check it reasonably quickly to verify if it is working correctly. To do that, simply input "about:config" into the Address Bar of your Firefox browser and press the Enter key on your keyboard. Next, accept the warning about changing advanced settings by clicking the "I'll be careful, I promise" button. On clicking the "Accept the Risk and Continue" button, a search feature will appear. Type in "javascript" into this search bar. As you type this, every JavaScript-based setting appear. If the "javascript.enabled" is set to "true," then your JavaScript is working correctly.

What happens if I disable JavaScript on Mozilla Firefox?

The use of JavaScript on your Firefox browser is virtually crucial because it enables the best use of modern websites such as Gmail, Facebook, YouTube, and more. If you have JavaScript disabled, most of what makes these websites work won't load in your Firefox browser. Some web page features such as buttons that change when they're clicked or images with zoom capabilities may not work properly while others may not work at all.

Chosen solution

By the way Options is the term used on Windows. On Mac, it's called Preferences and you can find it on the application menu ("3-bar" menu button) or the Firefox menu on the classic menu bar.

Also, I suspect you might have a filtering extension (e.g., ad blocker, tracking blocker, script blocker) that is causing this issue, but please work through the suggestions in cor-el's reply in case it's one of the simpler things.

Here's a screenshot of the website and the message I'm getting.

If you use extensions (Firefox menu button/Tools > Add-ons > Extensions) that can block content (e.g. Adblock Plus, NoScript, Flash Block, Ghostery) then make sure that such extensions aren't blocking content.

You can try these steps in case of issues with web pages:

You can reload web page(s) and bypass the cache to refresh possibly outdated or corrupted files.

  • Hold down the Shift key and left-click the Reload button
  • Press "Ctrl + F5" or press "Ctrl + Shift + R" (Windows,Linux)
  • Press "Command + Shift + R" (Mac)

Clear the cache and remove cookies only from websites that cause problems.

"Clear the Cache":

  • Firefox > Preferences > Advanced > Network > Cached Web Content: "Clear Now"

"Remove Cookies" from sites causing problems:

  • Firefox > Preferences > Privacy > "Use custom settings for history" > Cookies: "Show Cookies"

Start Firefox in Safe Mode to check if one of the extensions (Firefox menu button/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem.

  • Switch to the DEFAULT theme: Firefox menu button/Tools > Add-ons > Appearance
  • Do NOT click the Reset button on the Safe Mode start window
