The add-on themify allows you to set a 5px border of your webpages and set a background color between - no border, red, green, purple and blue. It shows a popup window first for you to make a selection and then executes the selection you make.
It is a very simple and easy to use add-on and provides a good foundation for beginners to create their own add-on. We encourage you to download the source code and have the add-on perform other more or less complicated tasks! Here are the steps to download and use this add-on:
- Clone the repository onto your machine in a place of your choosing.
- Test out this add-on by loading it temporarily on Firefox
- Open the about:debugging page on Mozilla Firefox
- Select the 'This Firefox' option
- Click 'load temporary add-on'
- Select any file in the repository for the add-on to load into Firefox
- Test it out on any other website. Google
