5 stars but this f*cking music while searching......

I've recently lost access to my old Scrapbook by upgrading to current Firefox. I'm really confused by ScrapBee as have added it to my extensions but cant find any clues as to how to get it working, nor do i know how to recover the old Scrapbook files?

Bit of a complicated setup process that isn't clear from the start. You wonder what's going on while it doesn't work and eventually dig around in settings where you are told to find a script and run that, if you can figure out to run the .exe or the .bat. My experience after that was to have Firefox vanish and be forced to run a system restore. The second star is because it looks promising, but I won't try it again until I know it's been updated.

Unfortunately can't get it to work. It just sits there saying "Starting" and nothing happens. No reaction to any button I push. As it works for many users, the problem may be on my end, but since I cannot figure out, what the problem is, I will have to deinstall it again and stick with HTTrack.

Update: After the reply from Victor I checked it out again. Evidently after installing it as a Firefox Add-on it still needs to be installed locally (reading the instructions carefully I kind of understand that now, but it was not clear to me from the beginning). But after registering the RDF it now just sits there saying "Loading...". So it still is not working for me. But I will give an extra star for the really fast reply from the developer.
