Windows 10 Launch Ushers in Improved F12 Web Developer Tools
Microsoft Edge is about to take over for Internet Explorer, and with the new browser comes an updated set of F12 tools with streamlined CSS editing, cookie management and more.Microsoft Edge may have taken Internet Explorer's place in Windows 10 as the new default Web browser, but its F12 tools live on. Edge, which officially launches alongside Windows 10 next week and is currently available in preview builds of the operating system, contains a new version of the F12 development tools that makes it easier to explore and manipulate Web code. F12 is so named because it springs into action when a user hits the F12 key. F12 is a collection of seven tools that enable developers to view HTML code, troubleshoot problems and monitor a Web application's effect on a browser. They include an emulator that simulates various screen sizes and device types, a DOM (Document Object Model) Explorer, a debugger and a console for determining the status of code, along with performance, network and memory monitoring. One big behind-the-scenes change ahead of Edge's impending release is how Microsoft is handling F12's technical documentation going forward.
Microsoft Edge Program Manager Ruben Rios said the company's "F12 developer tools documentation is now part of the Microsoft Edge Dev site and fully available on GitHub," in a July 21 announcement. "From this point on, the docs will not only be influenced by your feedback, but you're invited to contribute and help shape our documentation going forward."
