Hi wml2, I'm sorry to hear about this problem. Could you first make a backup of your "bookmarkbackups" folder? I'll mention the steps in a minute. Next, have you exited and restarted Firefox since this problem started? If exiting and restarting Firefox doesn't help, please shut down and restart Windows. The point of this is to free any file locks and complete any deferred updates. If the problem continues, I suggest running the "Verify Integrity" function to check on the database that stored bookmarks and history. Steps for that below as well. '''''Backing up the Backups''''' Firefox makes approximately daily backups of your bookmarks. They are compressed, so not possible to open directly, but may be important for recovery. To back those up: Open your current Firefox settings (AKA Firefox profile) folder using either * "3-bar" menu button > "?" Help > Troubleshooting Information * (menu bar) Help > Troubleshooting Information * type or paste '''about:support''' in the address bar and press Enter In the first table on the page, on the Profile Folder row, click the "Open Folder" button. This should launch a new window listing various files and folders in Windows Explorer. Right-click into the '''bookmarkbackups''' folder and click Copy. Then open a folder outside of any Firefox folder (such as Documents), right-click a blank area, and click Paste. It's also worth taking a peek inside to make sure there are recent files (the file names contain a date). '''''Verify Integrity''''' Open Firefox's Troubleshooting Information page using any of these methods: * "3-bar" menu button > "?" Help > Troubleshooting Information * (menu bar) Help > Troubleshooting Information * type or paste '''about:support''' in the address bar and press Enter Near the bottom, there is a section titled '''Places Database''' -- that's the file which stores history and bookmarks. Click the button labeled '''Verify Integrity'''. There may be a 10-15 second delay before results appear. If all is well, the report that appears below the button should start with: > Task: checkIntegrity + The places.sqlite database is sane + The favicons.sqlite database is sane Does yours say that, or something else? You can select and copy the report, and then paste it into a reply for review and comment.
