I can only speak for the Chrome/Safari WebInspector, and they're good, but I find myself going back to Firebug if I have to do any serious debugging - personally I find there to be a big step up in usability with Firebug meaning I can work faster.
It'll be interesting to see what happens to development tools when Firebug goes cross-browser.
> Why? What difference do you see between the browsers debugging-wise?
Feature-wise, very little. But as I said - I do find I can work faster with Firebug - I much prefer the the DOM inspector (one click node editing, css editing, the fact that it live updates the DOM as it is changed via any JS running on the page) and the console (DOM/JS object inspection and having XHR logging in the console itself and not on another tab). Plugins such as FireQuery also make a difference for my needs.
I'm not sure how anyone would be convinced that I find I can work faster with Firebug than other developer tools just by listing a bunch of features. shrug
Me too, Everybody has his or her likes..
Have been working pretty hardcore on web development for 10 years now but will stick with firefox for debugging because I use a lot of their tools, for example:
Firebug, Web dev Toolbar, HttpLiveHeaders, Rainbow and a couple more superior extensions..
