That definitely sounds frustrating especially if everything was working fine before the recent updates. Bookmark issues in Mozilla Firefox can sometimes happen after updates due to profile glitches, corrupted data, or extension conflicts. Here are a few things you can try that usually fix it for good: 1. Restart Firefox in Troubleshoot Mode Go to Help → Troubleshoot Mode. This temporarily disables extensions and custom settings. If bookmarks start working again, an extension is likely the cause. 2. Check Bookmark Toolbar & Library Press Ctrl + Shift + O to open the Library and confirm your bookmarks are still there. If they exist but don’t open, it may be a UI or profile issue. 3. Repair the Places Database Firefox stores bookmarks in a file called places.sqlite. Close Firefox Open your profile folder Rename places.sqlite to places.old Restart Firefox (it will rebuild it automatically) 4. Create a New Profile (Best Long-Term Fix) Sometimes updates corrupt the existing profile. Type about:profiles in the address bar Create a new profile and test bookmarks there If it works, migrate your data over 5. Disable or Remove Problematic Extensions Ad blockers or bookmark-related add-ons can interfere after updates. 6. Make Sure Firefox is Fully Updated Go to Settings → About Firefox and ensure you’re on the latest stable version.
