Honestly, now that I think about it, my biggest gripe is that Firebug lite on Chrome feels like an add-on. On Firefox, it feels native, and thus more usable (to me).

I've toyed around with various bookmarklet utilities to aid front-end developers. Firebug lite feels like one of those to me. I (maybe wrongly) perceive those as lightweight utilities.

Based on your comment, it sounds like my issue may be more with usability than functionality. I haven't even given the lite version enough of a chance since I didn't realize the JS debugger might be superior.

For the record, most of the time I'll use Firebug to tweak/debug some CSS. I'll also use it to track down JS issues. I've recently started to use it for server-side debugging with a couple php extensions.

Right now, Chrome is my primary browser (OSX). I'd love to use it exclusively, but I still find myself bouncing between the two when developing. (Sometimes I find myself getting lost in a cycle of Safari, Chrome and Firefox windows, but that's a whole 'nother issue.)

Edit: Fixed my use of parentheses.
