Web Developer Toolbar

What does your page/site look like in a browser other than your default one? If you use Internet Explorer, have you checked to see how your pages look in Firefox? In Opera or Chrome? If not, you may be in for a BIG surprise. You should be checking your site in at least one other browser preferably all of the major browsers.

If you are a developer of web pages, then one of the indispensible tools you can use is the web developer toolbar. The Web Developer extension adds various web developer tools to a browser. The extension is available for Chrome, Firefox and Opera, and will run on any platform that these browsers support including Windows, OS X and Linux.

What do these tools do? The Web Developer extension adds a menu and a toolbar to the browser with various web developer tools. What you can do will depend on which one you are using BUT all of them will let you validate your page - locally and/or online; resize your browser window, view the style sheet for the page/site or the source code.
