Hi You need a backup copy of places.sqlite to restore the history. Because places.sqlite stores bookmarks and history, you will lose bookmarks that aren't included in this copy of places.sqlite. You can look at a utility to browse System Restore points. *https://www.shadowexplorer.com/ ---- You can use the button on the "Help -> Troubleshooting Information" (about:support) page to go to the current Firefox profile folder or use the <b>about:profiles</b> page. *Help -> Troubleshooting Information -> Profile Folder/Directory:<br>Windows: Open Folder; Linux: Open Directory; Mac: Show in Finder *https://support.mozilla.org/en-US/kb/profiles-where-firefox-stores-user-data
