To think in the past times of the pre-firebug era it's pretty scary. Thanks for this tool!

FireBug is the DeFacto WebDeveloper / Designer tool. an out-FOXTROT-standing ADDon. I am an Internet Taxidermist by trade, and Interactive Media Design Student. I've shared FireBug with my fellow students, web and non-web majors, and nothing but enlightenment has followed. Being able to send the bug in and view the page structure visually has unraveled the mysteries of CSS for many here. (Thanx)

1.3.2 buggy Rated 4 out of 5 stars

Apart from the problem with downloads freezing at 99%, I discovered another problem: google ads on my site would not display, or displayed randomly. This problem appeared a day or so after I linked my google adsense and analytics accounts, but went away when I disabled Firebug (which is a must-have extension for any web developer).

So I don't know if it is purely a Firebug issue, or related to some buggy Analytics code ... there have been reports about a function failing in recent Analytics releases (Firebug complains about _gat._getTracker()).

Looking forward to the bugfix release :-)

Please Fix Rated 4 out of 5 stars

This is very good addon, but it has a bug that freezes your downloads at 99% most of the time. Please fix.

Tremendous!

Saves a lot of time!

With Firebug, you can test CSS, Javascript, etc. and make changes to your code without the need to reload the browser and upload files to a server!

When it comes to making lots of CSS tweaks, this is very handy.

Imprescindible

My rating is for the idea and for the version 1.2.1. The whole stable 1.3 and 1.4alpha-versions produce more overhead and are a pain to use. I'll never understand why the developers had to mess the brilliant 1.2.1 version up. Fixing bugs would have been enough.

1.3.2 Crashed FireFox Rated 5 out of 5 stars

I agree with Swilk, wait for a bug fix update. I updated from 1.3.1 to 1.3.2 and my Windows FireFox 3.0.6 would stall after running for 60 seconds (pages would stop updating), and would have to be entirely closed and opened to get another minute of use.

Went back to 1.3.1 - wait for the next update.
