I'm uninstalling Firebug today as I have not used if for a few months.
The integration with the built in inspector is great and logical, but I'll still miss Firebug somehow.
I have been using Firebug for about 9 years now and I feel a bit sad to be honest.
So as a "goodbye message" I would like to say to
Joe Hewitt and all other contributors to Firebug;
Thank you, for creating and maintaining such an awesome tool!
Thank you so much! Timo
