How to i restore my bookmarks

Sorry, that can be frustrating, especially if you had a lot of bookmarks saved. If you reset Windows, your old Firefox profile may still be available, depending on how you reset it. I'd check a couple of things first: 1. Open Firefox and go to Bookmarks → Manage Bookmarks to see if anything is still there. 2. If they're missing, check whether you had Firefox Sync enabled. Sign in with the same Firefox account you used before and see if your bookmarks sync back. 3. If you chose the Windows option to keep personal files, check whether there's an old Firefox profile in `C:\Windows.old\Users\[your old username]\AppData\Roaming\Mozilla\Firefox\Profiles`. If you find an old profile, its `bookmarkbackups` folder may contain a backup of your bookmarks. Don't delete anything from it yet. Did you choose Keep my files or Remove everything when resetting Windows? That makes a big difference in what might still be recoverable.
