Does a website tell you that you need JavaScript to view the page properly? If JavaScript is not available, it can sometimes cause problems when filling in online forms, or you notice that certain buttons or other elements are missing. JavaScript is an essential part of many websites and you need it to fully enjoy your internet experience. You may have turned it off to protect your privacy, so if you want to reactivate it, follow this guide for your browser of choice.

To step

Method 1 of 5: Internet Explorer

1. Click on the Gear icon in the top right corner. Select Internet Options from the menu.
2. Click the Security tab. Click on “Custom level” at the bottom of the window. The Security Settings dialog box appears.
3. Look for the Scripting category. Select the Enable option under “Active scripting”. This ensures that Internet Explorer can display JavaScript elements on the page.
4. Click OK twice to close. Click the Refresh button to reload the web page with the new settings.

Method 2 of 5: Chrome

1. Click on the Chrome menu button. This is the top right button that looks like 3 horizontal bars. Select Settings from the menu.
   • Alternatively, you can also do the following: type chrome: // settings / in the address bar and press Enter.
2. Click on the link “Show advanced settings”. In the Privacy section, click on the “Content settings…” button. This will open a new window.
3. Find the part of JavaScript. Make sure “Allow all sites to run JavaScript (recommended)” is checked.
4. Check your exceptions. The website you are trying to load may have been added to your exceptions list, causing JavaScript to not load even though it is enabled in the browser. Click on the "Manage exceptions ..." button and search for websites that do not belong there.

Method 3 of 5: Firefox

1. Make sure you don't have any browser extensions enabled to block JavaScript. Firefox has JavaScript enabled by default and you can usually only turn it off by running an extension. To see which extensions / extensions you have installed, click the Firefox menu and select Add-ons. This will open the Add-ons Manager.
   • Click the Extensions tab on the left side of the window. Some popular JavaScript blockers are: No-Script, QuickJava, and SettingSanity.
   • Click the extension blocking JavaScript and click Disable or Remove.
   • Restart Firefox and try to load a web page with JavaScript.
2. Check Firefox advanced settings. There is an option to turn JavaScript on or off, hidden deep in the browser's configuration files. To make sure this option has not been accidentally turned off, type about: config in the Firefox address bar and press Enter.
   • Suffer the warning and click the "I'll be careful, I promise!" button. Changing these files and settings can render your Firefox installation unusable.
   • In the search bar at the top, enter the following: javascript.enabled. .
   • The value of javascript.enabled should be set to “true”. If it is set to "false", right click on it and select Toggle.
   • Restart Firefox and try to open a website that uses JavaScript.
3. Reinstall Firefox. If nothing works, uninstall and reinstall Firefox to restore all default settings. Since JavaScript is a basic part of the Firefox browser, reinstalling should restore functionality.

Method 4 of 5: Safari

1. Click on the Safari menu. Select Preferences and then click on Security tab.
2. Make sure Enable JavaScript is checked. If this box is unchecked, JavaScript will be unavailable.
3. Activate Java on your iOS device. Tap Settings and scroll down to the Safari section. Tap Advanced, and turn the JavaScript option ON.

Method 5 of 5: Opera

1. Click on the Opera menu. Hover your mouse over Settings.
   • If there is no Opera menu but a traditional menu bar, click on Tools.
2. Hover your mouse over Quick Preferences. Check the box with Enable JavaScript.
3. Refresh your current web page. This will load the new settings.

Tips

• Java and JavaScript have nothing to do with each other and you should activate them separately.
