I love my current Firefox settings, bookmarks, folders and color, background image, dark mode. All I want to do is to create a Firefox browser backup file. I don't want to restore or sync anything. I just want a backup file in case of computer failure to restore to my next computer if ever necessary. I'm using Windows 10. I think they used to be "json" files? The only "Backup" link in the menu only addresses Restoring from a file. I just want to create a backup file for this current browser just the way it is. Is there a simple solution? Thank you SO much!!
