Passing by Mozilla's addons, checking my latest bookmarks' url, I just realized I forgot to say a warm thank you !!!
I'm using Password Exporter since at least 6 or 7 years, and it saved me a lot time, as I sometimes fully reinstall Firefox.
The first time Add-on Compatibilty Reporter told me PassExp doesn't work anylonger, I remember I had almost a heart-attack (joking.... but I've got plenty of passwords); you're kidding me !
Then I deactivated this unpleasant M(aster)F(inal) A-oCR as usual... and everything was fine again. Could reintroduce my passwords, within a minute ! Yes !!!
Therefore as we're used to say in French, better late than never : Thank You !
