You can transfer bookmarks using two different formats: * Backup format: if you want to preserve tags, this format can do that. However, the Restore process completely replaces all existing bookmarks with what is in the backup. If you want to merge different sets of bookmarks together, do not use this method. More info: ** [[Restore bookmarks from backup or move them to another computer]] * Export format: with this option, Firefox creates an HTML file with an ancient format compatible with most browsers. It is not as complete as the newer Backup format. More info: ** [[Export Firefox bookmarks to an HTML file to back up or transfer bookmarks]] ** [[Import Bookmarks from a HTML file]] Neither of these files contains cookies or passwords.
