Ooh please please ajust it so it keeps working with the new version of FF!!
Guys, your notes are still in your computer, il the repository folder. Look for the qfn.sqlite file. You'll need a special application to read that if you wish, but it might be easier just to install an old version of FF (or a portable FF) with QuickFox on it, use the settings to change the repository to where is your qfn file, and then copy your notes out.
Personally, i use Thunderbird for email and the addon still works with the current version.
