In addition to most browser makers focusing on the everyday user looking to surf the Web, they also cater to the Web developers, designers and quality assurance professionals who help build the apps and sites that those users are accessing by integrating powerful tools right into the browsers themselves. Firefox's Web Developer section includes tools for designers, developers, and testers alike such as a style editor and pixel-targeting eyedropper. Recently the Firefox team has lead the Dev Tools pack with tools for Grid, Flexbox, and more.
