Rated 3 out of 5 stars

With the "door hanger" display the Print button goes directly to the "native print dialog" box, no way to change the "Scale" via Page Setup or Print Preview (unless that already set for something else that was printed and wasn't reset to the default). Base font is just too large, IMO. My first print out was 4 pages long and all I added was Install Date

All types of Add-ons are lumped together, and the whole list is alphabetized. Extensions are intermixed with Appearance (Themes) and with Plugins, along with User Styles, and possibly GreaseMonkey scripts and "Social". It is possible to do a single Type output, like Extensions only but no "Type" listed for UserSyles or other then the "main" 4 Types.No way to include the Profile name, for users who are running multiple Profiles. for whatever reason.

Overall, a good start but not as friendly as the old InfoLister that many long time Firefox users have been using for over 9 years. ALD or ELD pales by comparison for power users who may have 50+ extensions, a lightweight theme or two and a few dozen UserStyles, along with some GM scripts.
