How to view the web server http response size in KB?

Question

I include jquery, jquery-UI and some jquery plugins in my website and I'd like to know the size in kb of each response, specially the first one. How can I see it in Firefox, Chrome and IE8?

Thank you.

Google Chrome

Open Chrome Developer tools by pressing F12 and select Network .
Size column is the one you're interested in.

Firefox

Install Firebug and open it by pressing F12 and select Net tab.
Size column is the one you're interested in.

Internet Explorer

Why would you want to see server response sizes in IE when you already got that information from the other two browsers? ;-)

No direct support in IE8 (or older for that matter). Use Fiddler local proxy tool when you can't use other browser.

Fiddler

It is actually a very powerful tool (browser independent) so you can use it with any requests going from your machine to some web server. These requests may be initiated by a browser (any) or your desktop application that makes requests to some web server. That's why this tools is invaluable to any developer since it provides many many features. You can even make requests directly from it.
