Most websites rely on special features to animate menus and play sounds. JavaScript is a programming language used to enhance web content and it is used to display this multimedia content. If you see errors on websites, such as incomplete images or stuttering slowing down your Firefox browser, it's probably because JavaScript has been disabled. You can turn it back on in one of the browser's advanced settings menus. If the classic repair methods don't work, you can try a different one.

Steps

To know your version of Firefox, press alt = "Image" + H to open the Help menu, then click on About Firefox.

Then type javascript.enabled. All the settings you can change will be displayed in alphabetical order. Each parameter has a mention under the Option Name, Status, Type and Value headers.

  • Another way to search is to click once on one of the settings under Option Name and then press the j. The page will automatically scroll to the first parameter that begins with "j". Keep typing "javascript" to scroll down to the option you are looking for.
