I was once a firebug too!

Finally, a FireBug solution for non-Firefox browsers!
Its not a plug in, so it only works for sites that you have access rights to hook in a JS include, but for development purposes, I’m stoked.
I use Safari for the majority of my browsing and such, so i am annoyed when I want to simply test padding/margin spacing on the fly or whatever, I have to fire up Firefox. Now hopefully I won’t have to.

I have yet to implement it but first thing when I get home….

Thanks for Tyson for the heads up!
