What unique features does Firebug have that are not built-in to Firefox?

Question

I just cleaned my Firefox addons and wondered:

• Which features does Firebug have that make it unique?

• Which features are available in both Fire

Answer 1

I think the biggest advantage still --after the implementation of Network Panel & Timeline functionality-- is the availability of various Firebug Extensions, like for example YSlow, Page Speed, FirePython and so on.

In the end it's probably more a choice based on your personal preferences, to come up with a weapon of choice that brings you most convenience and speed.

An interesting detail on this decision is, that Firebug once was one of the plugins that had most significant negative performance impact on Firefox. I don't know about a current study on that, especially if built in dev tools are acting better performance-wise than Firebug.

Answer 2

The console command line in large, editor mode allows running code against the current context. The new Scratchpad does not see the current breakpoint scope. This is a terrible loss.
