Bug report - the extension is configured to upload bookmarks to Box.net as soon as the login and password information is saved. This works fine for the first installation instance, however, subsequent installations on other browser instances will overwrite bookmarks.xml with the bookmarks from the current browser. This can lead to bookmark loss, especially if the user is unaware of this behavior. The first upload should be manual, the first download should be automatic. After that, bookmarks.xml should only be uploaded upon closing and only if bookmarks were changed.
