My number one add-on Rated 5 out of 5 stars

As a webdeveloper, Firebug is my number one add-on.
I use it almost every day! It's a perfect tool!
Alas, since today an update of ADB helper (version 0.72) is killing Firebug. So I needed to disable ADB helper.

SeaMonkey support is crucial Rated 1 out of 5 stars

Current version is fine but it is very disappointing to hear that Firebug 3 will not support SeaMonkey because it will just basically be a theming of Firefox's built-in devtools. This is the WRONG way for Firebug to be going, and it calls for a fork. I actually prefer the current UI to the proposed new UI, anyway.

It's little bit complicated - first few hours with firebug can be frustrating, but it's learning process.
