I am not computer savvy as a warning. I have Firefox as my browser. I am having trouble because my email Yahoo and other situations are not working right because they say, " 'Java Script' is not enabled." I did not even know what Java Script was. How do I enable Java Script or what is a substitute that Firefox recommends that will work like Java Script? Thank you

JavaScript is a built-in component and enabled by default. If a website complains that JavaScript in disabled then usually this is because you have a content blocking extension that blocks specific JS files.

If you use extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) that can block content (Adblock Plus, NoScript, DuckDuckGo PE, Disconnect, Ghostery, Privacy Badger, uBlock Origin), always make sure such extensions do not block content.

You can check for issues with Enhanced Tracking Protection. Firefox shows a purple shield instead of a gray shield at the left end of the location/address bar in case Enhanced Tracking Protection is blocking content.

  • click the shield icon for more detail and possibly disable the protection

You can check the Web Console for relevant-looking messages like blocked content.
