Internet Explorer Developer Toolbar Beta
This is pretty cool. I haven't done serious web development for almost three years now (!), but if I were still doing it, I'd want this. Download the freely available Internet Explorer Developer Toolbar, and add the following capabilities to your browser (from the site):
- Explore and modify the document object model (DOM) of a Web page.
- Locate and select specific elements on a Web page through a variety of techniques.
- Selectively disable Internet Explorer settings.
- View HTML object class names, ID's, and details such as link paths, tab index values, and access keys.
- Outline tables, table cells, images, or selected tags.
- Validate HTML, CSS, WAI, and RSS Web feed links.
- Display image dimensions, file sizes, path information, and alternate (ALT) text.
- Immediately resize the browser window to a new resolution.
- Selectively clear the browser cache and saved cookies. Choose from all objects or those associated with a given domain.
- Choose direct links to W3C specification references, the Internet Explorer team weblog (blog), and other resources.
- Display a fully featured design ruler to help accurately align objects on your pages.
While I'm on the subject, I always found ProxyTrace and Fiddler to be very useful tools. They both allow you to log and inspect HTTP traffic, something that too many developers tend to ignore.
