Enabling User JavaScript

  1. User JavaScript is a tool in Opera used to modify Web pages via code on your computer; it makes for lots of tip opportunities! To enable it, start by going to opera:config#UserPrefs|UserJavaScript and checking the box.

  2. In order to actually use scripts you need to specify the folder where Opera will look for script files. You’ll need to type a path in the field marked “User JavaScript File”. A good idea might be to create a folder inside your Opera preferences folder and use that.

  3. To apply the changes click the “Save” button. Opera will now execute any User JavaScript files copied to the folder you specified.
