Answer 1

I use firebug most of the time with the following firebug plugins.

• FireRainbow, FireRainbow enables javascript syntax highlighting for Firebug. This is really cool. Saves a lot of time.

• FirePHP,FirePHP enables you to log to your Firebug Console using a simple PHP method call.

• Widerbug, can leverage wide screens for js debugging/development. Obsolete now as it is supported in Firebug 1.9 right out of the box.
