First, could you make some extra backups, one each in the JSON and HTML formats: * [[Restore bookmarks from backup or move them to another computer]] * [[Export Firefox bookmarks to an HTML file to back up or transfer bookmarks]] Next, could you run the "Verify Integrity" diagnosis and repair function. That's here: Open Firefox's Troubleshooting Information page using any of these methods: * "3-bar" menu button > Help > More Troubleshooting Information * (menu bar) Help > More Troubleshooting Information * type or paste '''about:support''' in the address bar and press Return 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 > Task: checkCoherence + The database is coherent 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.
