Ask HN: What do you use Firebug or Chrome developer tools?

Chrome dev tools because I don't have to install anything.

(Though I am using firefox 4 beta for browsing now)

Firebug - I'm used to it, it works. Inspector doesn't have as many features as Firebug, either. Nor is it extensible.

All that aside, I'm not convinced that Google won't just forget that they have a browser.

Both, because I have to test both browsers. Fortunately, I don't have to support IE at all in my job.

I wish I could get the browsers I do have to worry about down to just WebKit, though.

Chrome devtools. Because for me chrome is far better browser.

WebKit Inspector, mainly in Safari.

Firebug does the job for me.

Dragonfly (Opera)

all three: Firebug (my main one), then Chrome tools, then IE dev tools (really). This helps me support all three browsers accurately.
