Being a developer, this tool is fantastic at helping me figure out what is causing the biggest drain on load times. Unfortunately, even the 0.3.3.3 version has not fixed the “unknown size” issue in the most recent versions of Firefox (currently 27.0.1). Hopefully this will be fixed soon, as this is one of the most useful tools I have found in the add-ons.
