Rated 5 out of 5 stars
This add-on is really outstanding!
I've used it (and the original scrapbook earlier) to archive a lot of pages for easy referencing anywhere I may be.
There is one small improvement I request to be included: Support for Relative Directories.
Whenever I run this add-on from my flash drive using FirefoxPortable on a different computer, I have to reconfigure the scrapbook's data location and this is quite frustrating sometimes.
If you could possibly add support for relative directories (such as relative to the firefox executable path), I think it would be very helpful for firefox portable users.
