The extension is actually a large collection of various tools for a Web master. Using Web Developer, you can get extensive information about page elements: link details, size, attributes, and colors. Web Developer can highlight any kind of elements (for instance, block-level ones and tables). You will even find a ruler utility to measure anything on a page. The add-on allows you to validate style sheets and HTML code of a page. Finally, you can use Web Developer to enhance the look of a poorly designed page. It lets you linearize a page, hide the background, and enforce large fonts. The extension installs a toolbar that accelerates access to the utilities. The extension will primarily interest Web masters but common surfers may use it for making pages more readable.
