Javascript that detects Firebug?

Question

What\'s a surefire way of detecting whether a user has Firebug enabled?

Answer 1

It may be impossible to detect.

Firebug has multiple tabs, which may be disabled separately, and, are now not enabled by default.

GMail as it is can only tell whether or not I have the "console" tab enabled. Probing further than this would likely require security circumvention, and you don't want to go there.
