Rated 4 out of 5 stars

Very cool idea. I can definitely see myself using this in my next project.

I wish I could remove the icon from the lower right corner of the window. Since this has a tab within Firebug, the Firebug icon in the bottom corner should be sufficient.

This review is for a previous version of the add-on (0.5.2). 

Remove status icon

Added in latest version (0.5.4). Set it in options menu.
