What to do if…
your browser bookmarks, history, or extensions disappear after an update

Short answer

Pause and avoid reinstalling or “resetting” the browser. First confirm you’re using the correct browser profile and that sync hasn’t swapped you to an empty or older copy.

Do not do these things

  • Don’t uninstall/reinstall the browser yet (it can overwrite local recovery files).
  • Don’t use “Reset settings”, “Refresh”, or “new profile” as your first move.
  • Don’t repeatedly toggle sync across multiple devices (it can spread the wrong version everywhere).
  • Don’t run “cleanup” utilities that delete browser data/profiles right now.
  • Don’t start installing random “recovery extensions” (they can add risk when you’re stressed).

What to do now

  1. Stabilize (one minute).

    • Stop clicking around. Don’t clear cache/history.
    • Close extra browser windows to reduce accidental changes.

  2. Check you’re in the right profile (most common cause).

    • Look for the profile icon (often top-right). If it says Guest or shows a new profile name, switch back to your usual profile.
    • If there are multiple profiles, open each briefly to see if your bookmarks/extensions are there.

  3. Find the “good copy” before you let anything sync.

    • Check another device where you normally use the same browser/account. If that device still has the right bookmarks, treat it as your reference copy.
    • On the device that looks “empty”, avoid “reset sync” and repeated sign-in/out loops until you’re confident you’re not about to overwrite the reference copy.

  4. Check sync status carefully (avoid “reset sync” actions).

    • Confirm whether you got signed out during the update and whether bookmarks/favorites and extensions are selected to sync.
    • If your reference device has the correct data, keep it stable while you bring the “empty” device back into line.

  5. Use built-in restore/backup options where available.

    • Firefox: use the Bookmarks Manager “Restore” option to restore from automatic backups.
    • Chrome/Chromium-based browsers: check the Bookmark Manager for “Other bookmarks” and any imported/restored folders.
    • Edge: confirm Favorites sync is enabled and restart the browser once; sometimes it reappears after a short delay.

  6. If extensions disappeared, check whether they were disabled.

    • Open the extensions page and look for disabled items you can re-enable.
    • If the browser indicates extensions are disabled by policy (work/school management), treat it as a managed-device setting and contact IT rather than fighting it.

  7. If you suspect account compromise (unexpected sign-out, unknown extensions, changed search engine/homepage, security alerts):

    • Change the password for the browser account (Google/Microsoft/Firefox account) and enable two-factor authentication if available.
    • Review recent sign-ins and connected devices for that account.
    • Run a reputable security scan.

  8. If you believe this involved cyber-enabled fraud, theft, or identity misuse:

    • To report internet crime to the FBI, file with IC3. To reduce the risk of scams, type the address directly (ic3.gov / complaint.ic3.gov) rather than clicking links from emails, texts, or search ads.
    • If identity theft is involved, use the federal government’s identity theft resource to create a recovery plan and report.

What can wait

  • You don’t need to decide today whether to rebuild bookmarks manually or switch browsers.
  • You don’t need to “clean up” the computer or optimize anything right now.
  • You don’t need to reset sync or wipe profiles as a first response—those steps can make recovery harder.
  • Once recovered, you can later export bookmarks and note your sync settings—but don’t do that while you’re still unsure which copy is correct.

Important reassurance

This usually has a mundane cause: the browser opened a different profile, sync signed you out, or the update disabled items. Going slowly prevents turning a recoverable problem into permanent loss.

Scope note

These are first steps only, meant to stop the damage and locate a good copy (profile/sync/backup). If these don’t resolve it, the next stage is careful, browser-specific recovery from profile folders and backups (best done deliberately, or with help).

Important note

This is general information, not professional IT or legal advice. If your device is managed by an employer/school, use their support channels. If you think a crime occurred, prioritize account security and appropriate reporting.
