What plugins improve Google Chrome as a web developer's browser?

Question

The usual recommendations for a web development and debugging web browser are Firefox/Firebug or Safari/Web Inspector.

But I like Google Chrome, and would like to use this as my primary development browser. What plugins or tools should I get to optimise my web programming experience with Chrome?

Answer 1

Google Chrome's own "Firebug" is very good, just right click and inspect element to bring it up.

Frame two pages is helpful.

Chris Pederick's Web Developer toolbar is good too.
