Rated 2 out of 5 stars

This extension has been poorly documented from the beginning. Add to that the recent problems with updates related to browser and Firebug versions. Version 0.6.* of this extension requires Firebug 1.8+. Firebug 1.8 requires Firefox 5. However, this extension automatically updates on old browser and extension combinations, like Firefox 3.6 with Firebug 1.7!

This review is for a previous version of the add-on (0.6.1). 

The compatibility issues have been fixed. See: http://groups.google.com/group/firephp-dev/browse_thread/thread/869b20019b33db3c
