How to Check for Javascript Enabled

By Lysis

Javascript is a client-side programming language that is used on websites. Javascript is turned on by default when you install Firefox or Internet Explorer. Javascript is used for some malicious activity on websites that host malware, so some users prefer to disable Javascript for better security on their machine. You can disable and enable Javascript in the Web browser's settings. To check if Javascript is enabled, you simply need to view the browser's properties.

Internet Explorer

Step 1

Open Internet Explorer. Click the "Tools" menu item and then select "Internet Options."

Step 2

Click the "Security" tab. This tab is where you enable and disable different Web browser elements and block unwanted websites to protect your machine.

Step 3

Click the "Custom Level" button. This opens a new window. Scroll down to the "Scripting" option. If the check box is marked, then you have Javascript enabled. You can disable Javascript by removing the check mark.

Firefox

Step 1

Open Firefox. Click the "Tools" menu option and then select "Options." This opens the browser's property settings window.

Step 2

Click the "Content" icon at the top of the window. This displays a new tab in the properties window.

Step 3

View the list of options. If a check mark is next to the section labeled "Enable Javascript," then you know Javascript is enabled. Remove the check mark if you want to disable it.

Tips & Warnings

  • Disabling Javascript can cause websites to stop working properly. Some website developers use Javascript for menu design, so without it enabled the navigation on the page will not work.
