How to enable JavaScript and cookies in Firefox?

Enabling JavaScript and cookies in Firefox is straightforward and can be done through the settings menu. Here's how:

Enabling JavaScript

There are two primary ways to enable JavaScript in Firefox: through the configuration editor (about:config) or, the much simpler and recommended method, through the Privacy & Security settings.

Method 1: Using Privacy & Security Settings (Recommended)

This is the easiest and safest way to enable JavaScript. If you want to disable javascript for a particular website only, this will not help. You would need to use an extension.

1. Click the three horizontal lines in the upper right corner of the Firefox window (the menu button).
2. Click Options (or Preferences on some operating systems).
3. Select Privacy & Security on the left-hand side.
4. Scroll down to the Permissions section.
5. To allow JavaScript globally, ensure that "Block new requests asking to allow JavaScript" is unchecked

This method does not have a direct toggle to enable or disable javascript but instead controls whether websites can request permission to run Javascript. If it is unchecked, Javascript is enabled globally.

Method 2: Using about:config (Advanced)

Warning: Modifying settings in about:config can potentially affect the stability and security of your browser. Proceed with caution.

1. In the Firefox address bar, type about:config and press Enter.
2. You will see a warning message "Proceed with Caution". Click Accept the Risk and Continue.
3. In the search box that appears, type javascript.enabled.
4. If the value of javascript.enabled is false, click the Toggle button (the double arrow icon) next to it to change the value to true. A value of true means JavaScript is enabled.

Enabling Cookies

Here's how to enable cookies in Firefox:

1. Click the three horizontal lines in the upper right corner of the Firefox window (the menu button).

2. Click Options (or Preferences on some operating systems).

3. Select Privacy & Security on the left-hand side.

4. Under the Cookies and Site Data section, choose your preferred settings. The options include:

   • Standard: This is the default setting and allows most cookies.
   • Strict: Blocks most cookies that track you across websites, but some sites may not work correctly. You can customize this option further.
   • Custom: Allows fine-grained control over cookie settings. You can block cookies from specific websites or all third-party cookies. You also have control over when cookies are deleted (e.g., when Firefox is closed).

5. To ensure cookies are enabled, select either Standard or Custom, adjusting the Custom settings to your needs. If selecting Custom, ensure that you haven't selected options to block all cookies.

By following these steps, you can easily enable JavaScript and manage your cookie settings in Firefox.
