Enable JavaScript

The first step is to open Firefox. Next, click the menu button in the upper right corner and select "Options" from the drop-down menu. This will open the browser settings page.

In the left column of the Settings page, select the "Privacy & Security" tab. Scroll down to find the "Permissions" section. Here, you can see a checkbox called "Enable JavaScript."

Make sure this checkbox is selected. If it's not selected, just select it.
