I would have needed this to debug Rated 1 out of 5 stars

javascript. But this is impossible, as a javascript error is always shown once only. Every repetition of the same javascript error is simply NOT recognized by Firebug. So it is worthless for debugging. Don't use it, it will a great disappointment!

Brilliant! Rated 5 out of 5 stars

To be completely honest, I never really understood all the love and praise that Firebug received every day.

Then I discovered the "Inspect" and "Live Edit" features.

Holy. Crap.

Firebug easily cuts the time to edit a site or add a new feature in half. It not only eliminates the guesswork to figure out what css property is messing up your design, but it also allows you to see what'll happen if you remove X or add Y on the fly.

I can't recommend this plugin enough!

A great tool for web development, troubleshooting and learning. The live edit and inspect features are particularly useful.

Firebug previous version was awsome Rated 5 out of 5 stars

Since I upgraded to Firefox 3, it's no longer working properly, when you are debugging it randomly stops without having any breakpoint :(. Had to install firefox 2 again just to have this wonder working.

Fantastic addon. The only thing is that the toolbar button doesn't open the panel, but rather a new window. Is there a way to change this?
