Firebug is a fantastic tool. It works as an add-on to Firefox and can be used for all sorts of fun stuff. It is a javascript debugger (breakpoints, variables and watch expressions). It can also be used to “inspect” whatever web page you happen to be visiting (hover over areas of the page to see its corresponding HTML and CSS). It’ll even profile the javascript.
The original author, Joe Hewitt, open sourced Firebug sometime last year and back in mid-July, John Resig (a well-known javascript guru and Mozilla employee) announced that he was taking over its development. Today he laid out his initial plans:
- Improve the knowledge of Firebug that we have
- Build a runnable set of test cases to prevent regressions
- Track the state of Firebug performance
- Audit and Improve
I can’t wait to see how Firebug evolves now that Resig has reign.
