Outstanding! Just stop reading and install. Don't judge it until you've taken time to use it and learn it. Firebug is a HUGE time saver!!!

1.5 crashing when searching Rated 4 out of 5 stars

1.5 Firebug is crashing every time I use the built in search feature in Firefox. I've disabled all other add-ons with only Firebug enabled and it crashes. When disabled it's fine. Using 1.4 again until this is resolved. Other than that I absolutely LOVE this add-on :)

It goes without saying this is an amazing add-on. It's almost like a full-fledge IDE within your web browser. Firebug has saved me a tremendous amount of time when it comes to debugging JavaScript and HTML/CSS.
