Well done to Ray and Adam on releasing ColdFire RC1! ColdFire will display ColdFusion debugging info right inside Firebug. Head over to the RIAForge site to grab it:

ColdFire currently supports debugging information for:

General Information
Templates
Queries
CFTRACE

More is being added soon.

Three guesses at what I'll be installing at work today ;)
