issues with facebook app and facebook through edge working

Hello, thank you for reaching out to Microsoft Q&A.

1. Are you unable to access Facebook only when using the Microsoft Edge browser? Does Chrome or any other browser work?
2. Have you tried using an InPrivate (incognito) window to see if you can sign in successfully there?

In Microsoft Edge, press Ctrl + Shift + N to open an InPrivate window.

Then go to the Facebook website and try signing in to your account.

If you can sign in successfully there, please try clearing your browsing history, cache, and cookies in the normal browser window.

After that, restart your browser and try signing in to Facebook again in a regular (non‑InPrivate) window.

You can also try switching networks, for example, using a mobile hotspot, and check if you are able to sign in.

Follow these steps in order, testing Facebook in Edge after each step.

1. Clear cookies and cache for all time
   1. In Edge, go to edge://settings/privacy.
   2. Under Clear browsing data, select Choose what to clear.
   3. Select Cookies and other site data and Cached images and files.
   4. Set Time range to All time.
   5. Select Clear now and then restart Edge.
   6. Try signing in to Facebook again.
2. Check if security software is blocking Facebook
   1. Open any third‑party security software (for example, Norton or McAfee) installed on the PC.
   2. Check for any web protection, safe browsing, or firewall features that might be blocking or filtering Facebook and ensure they are configured to allow it.
   3. Make sure the security software is fully up to date.
   4. Try Facebook again in Edge.
3. Verify Edge and Windows are healthy
   1. Make sure Edge is up to date:
      • Select Settings and more (… ) > Settings > About Microsoft Edge and let it apply any available updates.
   2. Restart the computer and test Facebook again.
4. Repair Microsoft Edge
   1. Close Edge for all users on the device.
   2. Go to Start > Settings > Apps > Installed apps.
   3. Find Microsoft Edge, select it, then choose Modify.
   4. When prompted, select Yes, ensure the device is online, then select Repair.
   5. After the repair completes, open Edge and try Facebook again.
5. Check for network or site‑specific issues
   1. Try opening Facebook in another browser on the same PC.
   2. If it also fails, restart the modem/router and test again.
   3. If possible, test Facebook from a different network (for example, mobile hotspot) to see if the issue is network‑specific.

If Facebook still will not pass the login screen in Edge after these steps, capture the exact error message or behavior and use Settings and more (… ) > Help and feedback > Send feedback in Edge to report the issue, including that other sites work and MFA confirmations are received but login does not complete.
