Works with FX17 (-: Rated 5 out of 5 stars

This extension has been invaluable to me over the years with regard to helping debug extension conflicts and to catalog my extensions when I've had to create a new profile because my original became corrupted.

It's so brilliant in its simplicity. I cannot fathom how and why Mozilla hasn't incorporated this functionality into FX's about:addon page at any time over the years this extension has existed.
