With WebIDE, you can create, edit, test or debug web apps by running them on the Firefox OS simulator. If you are creating a new web app, it also creates a basic app boilerplate or a more complete boiler plate for you along with a proper directory structure.

You can check the responsiveness of your web application with the help of this utility. It offers a number of options such as setting the size of the device that you want to emulate, rotating the screen (shift from portrait to landscape mode), simulate touch events and taking screenshot of the webpage in the responsive mode.

The Eyedropper Tool is a really awesome tool which helps you to know the hexadecimal value of any color in a webpage (just like the eyedropper tool in Photoshop). This helps in finding the color of any element or image which having to browse through it’s code via Element Inspector. Clicking on the color copies it’s value to your clipboard!

Well, Browser Inspector is used for debugging the Firefox Browser itself. If you want to change the color of the URL bar or for instance change the curve of the tabs with non-persistent results, then you can do that through the Browser Inspector.

Scratchpad can be used to run clusters of javascript code and edit, run and examine the results. The way it differs from the Browser Console is that Browser Console, is designed for interpreting a single line of code at a time, but with Scratchpad you can work with larger chunks of code executing it in various ways depending on how you want to use the output.
