If you want to add a little more to your website than the default, Custom JavaScript for Websites 2 is the tool for you.

What can I do with it?

It lets you run custom JavaScript on any website, including your own. It works by simply adding the required code to the website.

Your code is stored in the browser and you can access it from any website, but only on your local computer.

It is not sent to the server and you cannot use it to mess with other people's websites or databases.

How do I use it?

There are two ways to use this extension.
