Look on your desktop. Do you see a folder called; '''Old Firefox?''' '''https://support.mozilla.org/en-US/kb/recovering-important-data-from-an-old-profile''' '''https://support.mozilla.org/en-US/kb/back-and-restore-information-firefox-profiles'''

Thank you for your answer. I know about Old Firefox files but there is not such a folder. I search for it but I not find it. Toni

To open the '''Bookmarks Manager,''' press the '''Alt''' or '''F10''' key bring up the tool bar, and select '''Bookmarks.''' Hot key is '''<Control>''(Mac:<Command>)'' <Shift> B.''' Select '''Restore.'''

Are there any backups in the bookmarkbackups folder? You can check for problems with the <b>places.sqlite</b> database file (bookmarks, history) in the Firefox profile folder. *Places Maintenance: https://addons.mozilla.org/firefox/addon/places-maintenance/ *http://kb.mozillazine.org/Bookmarks_history_and_toolbar_buttons_not_working_-_Firefox *https://support.mozilla.org/kb/Bookmarks+not+saved#w_fix-the-bookmarks-file If you use the Time Machine then try to restore file(s) from that backup. *http://www.apple.com/support/timemachine/ *https://support.mozilla.org/kb/Recovering+important+data+from+an+old+profile *https://support.mozilla.org/kb/restore-bookmarks-from-backup-or-move-them
