Rated 5 out of 5 stars

This is a useful Extension for tracking data transfers to the foreground Tab, where the user hasn't specific need for the advanced monitoring and tool capabilities of Firebug. In Classic style/Slim mode, I have full space for the Web page to be viewed.

No major problems encountered to date. When combined with Classic Compact, each datum has its own "box" in the Statusbar.

This review is for a previous version of the add-on (1.5.4).
