Incredible time-and-effort-saver. I've literally saved days in web development since I started using this plugin. And I don't even do front end stuff that often :-)

This is the most advanced addon I've seen for Firefox. This and the Web Developer addon are getting heavy use. Easy to use and actually takes a lot of the work out of coding and I've only scratched the surface with it so far. Every web coder I've shown it to is using it now.

agree to claudiopro. Firebug in addition to Web Developer is the best way to analyze css and debug your site.

@kris33 :

The one who's spamming is you, my friend. Instead of posting comments on each and every FF-addon, just ignore them if they offend you that much. It's ridiculous.

If you look at the number of Firebug users, you'll see that there's clearly a demand for this kind of software on iusethis. Accept that and stop behaving like a spoiled child.

The new 1.0 beta blows everything out of the water. Web development was never this easy!

Brilliant. Far slicker than Venkman, IMHO.

Excellent and very stable add-on. Must get it if you are still using "alert()" for JavaScript debugging.

This is my #1 addon together with Web Developer
