How to Enable JavaScript on Facebook

By Ty Arthur

Facebook is a popular social networking website that lets you post messages to friends and family. In order to take advantage of some of Facebook's features, such as the ability to chat through the built-in instant messaging program, you must have JavaScript enabled in your web browser. In most web browsers JavaScript is automatically turned off, but it's a simple and quick process to turn it back on. The steps for enabling JavaScript are slightly different depending on which browser you use.

Mozilla Firefox

Step 1

Click on the "Tools" button located at the left side of the toolbar at the top of the window. Scroll down through the drop-down menu and click the "Options" entry.

Step 2

Navigate to the "Content" tab in the "Options" window. Locate the series of check boxes at the top of the window.

Step 3

Check the box marked "Enable JavaScript." Click the "OK" button.

Step 4

Close down the Mozilla Firefox browser and then open it up again to enable the change. Navigate to the Facebook website and log into your account.

Internet Explorer

Step 1

Click on the "Tools" button at the upper-right corner of the Internet Explorer web browser. Scroll down and click on "Internet Options."

Step 2

Navigate to the tab labeled "Security." Click on the "Custom Level" button in the security options.

Step 3

Scroll through the list of custom security options and locate the heading labeled "Scripting." Click the "Enable" button next to the "Active Scripting" entry.

Step 4

Click the "OK" button at the bottom of the window. Close down Internet Explorer and then open it up again to save the security level change.

Step 5

Navigate to the Facebook website and enter your user name and password information.

Tips & Warnings

  • You can also bring up the "Tools" menu in the Mozilla Firefox web browser by pressing the "Alt" and "T" buttons on your keyboard.
  • JavaScript is normally set to be disabled in your web browser because of security concerns. While enabling JavaScript will allow you to use applications such as the Facebook website, it also leaves your web browser open to malicious software embedded in untrustworthy websites. Make sure to frequently update and run an anti-virus and anti-spyware program if you will be surfing the web with JavaScript enabled (see Resources).
