How to Turn on Javascript for YouTube

Youtube.com is an immensely popular video sharing website which requires the latest versions of Adobe Flash and Javascript. Javascript is often disabled to increase security, speed up browsing or to remove advertising. Youtube.com requires Javascript to enable the embedded streaming video. The settings to enable Javascript are found in the "Tools" menu. However, a scriptblocker such as NoScript, might also be unintentionally blocking the good scripts with the bad.

Things You'll Need

• Internet Explorer
• Firefox
• Script Blocker

Instructions

Internet Explorer

1. Open Internet Explorer. From the "Tools" menu, select "Internet Options."

2. Click the "Security" tab at the top of the window. Make sure "Internet" is selected as the zone, then click the "Custom Level" button in the "Security Levels for this Zone."

3. Scroll down to the "Scripting" options. Click the "Scripting of Java Applets" radio button to enable Javascript.

4. Click the "Ok" button to exit the "Security Settings: Internet Zone" window, and hit "Ok" again to exit the "Internet Options" window.

Firefox

1. Open Firefox and select "Options" from the "Tools" menu.

2. Click the "Content" tab located at the top-middle of the "Options" window.

3. Click the check box next to "Enable JavaScript" to allow scripts to run. Click the "Advanced" button to specify what exactly the scripts are able to do.

4. Click the "Ok" button to exit the "Options" window.

NoScript Script Blocker

1. Click the NoScript icon located at the bottom of the Firefox web browser. The NoScript icon is a blue "S" inside of a white circle. If scripts are being blocked, the icon will have a red line strike out.

2. Select "Allow Youtube.com" to add Youtube.com to the white-list of websites allowed to run scripts. A white-list is a list of websites specified by the user to be trusted enough to allow scripting.

3. Select "Forbid Youtube.com" to remove Youtube.com, or any other website, from the white-list.
