Review for Extension List Dumper by seaoffecundity
Rated 5 out of 5 stars
ironically i forgot what this extension was called, and when i came to install addons on my laptop i couldn't find it. i didn't know what to look for because 'add-on' and 'extension' are tagged on everything, and list and save are common too.
thus i think this is one of the hidden gems of firefox, everyone needs it but few have found it.
