Every modern web browser includes a powerful suite of developer tools. The Web Developer Toolbar helps you in debugging as well as to reduce the loading time of your site in different browsers. You have the option to check the rendering of the site for desktop and mobile versions, with options to manually adjust the screen resolution. These tools do a range of things from inspecting the currently loaded HTML, CSS to showing which assets the page has requested and finding out how those changes affect your website. The Developer Toolbar also helps debug JavaScript source code and frequently monitor events, evaluate output style, or measure your website's execution and load times.
