I'm having trouble cleaning out bookmarks in Firefox. I use the iCloud Bookmarks add-on, so that I can sync bookmarks between Firefox on my Windows computer and Safari on my iPhone. I'm sure part of the problem (or the entire problem) is that I have too many bookmarks. I'm trying to clean them out and delete ones I don't need, but they keep coming back. I've tried deleting them in Firefox and in Safari. I'm not using Firefox sync. I've been looking for the answer but can't find it.
