Rob starts by highlighting what's new in Firebug 1.4 alpha. It's a joy for me to see that activation (enabling and disabling) has been simplified. Rob points out that the firebug icon serves also as a menu. One of the menu items is "Open With Editor", which developers will find useful for saving changes to their pages. A much needed UI change is flipping the tabs and buttons. The tabs used to be below the buttons. Putting them at the top is closer to what users expect from working with other tabbed UIs.
Firebug Extensions provide a way for developers to add functionality that can be shared with others. Rob mentions several extensions including:
- Firediff - tracker for changes made to DOM and CSS
- FireCookie - cookie manager
- FirePHP - console logging from PHP
- YSlow - performance tips
