This is just excellent.
Over the years I've used everything from FEBE to screenshots to Notepad just to keep a list of my extensions.
Found this just a couple of days ago and it works a treat, thank you very much.
Many thanks also to CodeSlayer for the about:support tip... I hadn't looked at that before, which will also do what I want as well as telling me what extensions are in those folders with utterly unhelpful names.
