Mozilla recently announced the launch of a developer’s version of Firefox. It is targeted at web developers and includes WebIDE and the Valence add-on which allows you to connect the Firefox developer tools to other web browsers. Firefox for developers also includes a responsive design view that allows developers to test out multiple screen sizes easily without needing to resize the entire window. Overall, Firefox for developers is a good tool, but it doesn’t offer much that Google Chrome dev tools didn’t already have.
