CloseReview for Extension List Dumper by KR
Rated 4 out of 5 stars
I tried this in 2014, on Windows 7. It works for me. You will see a button in the addons manager, only on the "extensions" tab.
One improvement I'd like is to have hyperlinks to the addons.mozilla.org site where each can be installed. oh well.
