I utilize folders for organizing bookmarks. Twice now I have had one of my bookmarks deleted by Firefox and I do not know what to do to stop it. Unsure of what I was doing the first time when I realized it had happened. This time, just a couple of hours ago, I was organizing my bookmarks and it was there and I did put a new bookmark in it. When I was done I went into Firefox and opened the tab to make sure it was working correctly and after closed everything out. I did not delete anything but some older bookmarks and made sure that no folders were highlighted and in fact, the folder in question was there before I closed out of Firefox. I come back, without shutting my computer down, open Firefox and it was gone. This is at best frustrating and at worst makes me want to use another browser altogether.
