Hi tracor, A clean reinstall sounds like it would clear the profile. Unless you have a back up I am sorry, but the data cannot be restored. Do you see a profile folder from the previous install? *[[Profiles - Where Firefox stores your bookmarks, passwords and other user data]]

You can use this button to go to the current Firefox profile folder: *Help > Troubleshooting Information > Profile Directory: Show Folder (Linux: Open Directory; Mac: Show in Finder) *http://kb.mozillazine.org/Profile_folder_-_Firefox Do you have any compressed .jsonlz4 backups in the bookmarkbackups folder? You can check for problems with the <b>places.sqlite</b> database file in the Firefox profile folder. *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 *Places Maintenance: https://addons.mozilla.org/firefox/addon/places-maintenance/ ---- If you use the Time Machine then see if you can restore the file(s) from that backup. *http://www.apple.com/support/timemachine/ *https://support.mozilla.org/kb/Recovering+important+data+from+an+old+profile *http://kb.mozillazine.org/Transferring_data_to_a_new_profile_-_Firefox
