Folders are disappearing from Safari's Bookmarks Bar
Do you have iCloud turn-on for your bookmarks? I did and found horrendous anomalies with my bookmark folders between my iMac, MacBook Pro, iPhone, and iPad. I could not get the issue solved and so far no solutions for it. My only recurse was to turn off iCloud/Bookmarks and restore my original bookmarks from backup and sync with iTunes. That solved my problem.
