How to Turn on Cookies and JavaScript: Quick & Easy Guide

If cookies or Java are disabled in your web browser, websites may not display as intended. JavaScript and cookies are turned on by default in most web browsers, but many allow you to enable or disable them as needed. This How.com.vn teaches you how to turn on cookies and JavaScript in Chrome, Safari, Microsoft Edge, and Firefox on any device.

Allow third-party cookies (optional). If you only want to change your settings for third-party cookies, such as those that track you across websites, click Third-party cookies under "Privacy and security," and then select Allow third-party cookies.
- This does not enable all cookies if you've disabled them. Google has moved this setting to a more hidden area, which we'll go to next.
- Click the back button when you're finished to return to the previous screen.
It's under "Privacy and security."
If you don't see this option at the bottom of the menu, skip to the next step.
It's the last option on the page.

Select Allow sites to save data on your device. The first option on this page enables cookies throughout Chrome.
- Click the back button once to return to the previous page.
It's under the "Content" header.

Tap the three-dot menu ⋮ in Chrome. It's in the top-right corner of the screen. A drop-down menu will appear.
- Cookies and Java are both enabled on Chrome for iPhone and iPad by default. There's no way to turn either on or off—they are both always on.
- Chrome no longer has a simple "Cookies" switch. Instead, your browser allows you to enable or disable third-party cookies (those that track you across websites) or enable/disable "on-device site data." If you want to enable the useful cookies, such as the ones that keep you signed in to websites, you'll want to enable "On-device site data."
You may have to scroll down to see it.
You'll see it under "Advanced."
As long as this switch is enabled, websites can save cookies on your Android.^{[1]XResearch source}
It's in the top-left corner of the screen.

This option is near the middle of the Site Settings page.

Tap the grey JavaScript
switch. It will slide right and turn blue or green, which enables JavaScript on all websites.

It's the padlock icon at the top of the window.
If this box was already checked, there's nothing to change—JavaScript was on already. But if it was off, checking this box will turn it back on.

- If you'd rather not allow cross-site cookies to track you, select Strict instead. This could make websites act a little differently than expected, so if you run into problems, return to this screen and select Standard instead.

Community Answer
No, you are not able to enable JavaScript using Safari. If you download the "Puffin" web browser from the app store, it has JavaScript built in, so you can use it there.

In most web browsers, both cookies and JavaScript are enabled by default; you really shouldn't have to enable them unless you or someone else have previously disabled them.
