BackupHelper Plus for ScrapBook Plus / XSidebar is a modified version of the original ScrapBook Add-On BackupHelper, which you find here: http://amb.vis.ne.jp/mozilla/scrapbook/addons.php?lang=en#Backup
This version will work with ScrapBook Plus or with ScrapBook with XSidebar for Seamonkey but not with ScrapBook version 1.4.x or higher because of API changes in the original ScrapBook version. So don't use this add-on if you have installed ScrapBook version 1.4.x. Instead of ScrapBook version 1.4.x use ScrapBook Plus version 1.8.18.x.
You find ScrapBook for Seamonkey with XSidebar here: http://xsidebar.mozdev.org/modified.html#scrapbook
You find ScrapBook Plus for Firefox here: https://addons.mozilla.org/en-US/firefox/addon/scrapbook-plus/
Before you can use this add-on you have to uninstall the original extension BackupHelper. Don't enable both extensions BackupHelper and Scrapbook BackupHelper Plus at the same time!
