I do not use seamonkey but it now uses the same type of bookmarks (see http://www.seamonkey-project.org/releases/seamonkey2.1a3/changes ) as firefox there is the posibility you could use [[what is firefox sync?|sync]] to sync bookmarks. Whatever you do it is probably worthwhile manually backing up the bookmarks first of all. * see [[backing up and restoring bookmarks]] Seamonkey will I understand export html bookmarks. Firefox will then import those * Firefox Button -> Bookmarks -> import... -> import from HTML <br> imported html bookmarks will be placed in a folder within the firefox bookmarks library.
