Excellent Product Rated 4 out of 5 stars
I use this regularly; it's much easier to perform a search in ScrapBook then search each bookmark. I can still do research (or be amused) when I don't have an internet connection.
Two "buts": After reinstalling XP and reinstalling Scrapbook (from FF), I couldn't retrieve my saved folders. I downloaded the tutorial and learned how, but it's complicated enough I haven't tried it yet. When I added notes, I couldn't see them until I finished (clear text?).
I would like more control over the notes and editing, but it's the best extension, hands down, I've found for saving full pages and pieces of pages.
