How to delete notifications on Facebook ?

 To delete notifications on Facebook, you can follow these steps:

1. Open Facebook: Log in to your Facebook account on the Facebook website or mobile app.

2. Access Notifications: Look for the notifications icon, which typically looks like a bell icon. On the website, it's usually located in the top-right corner of the page. In the mobile app, you can find it at the bottom of the screen on iOS devices or at the top on Android devices.

3. View Notifications: Click or tap on the notifications icon to view your notifications. This will display a list of recent notifications you've received.

4. Delete Notifications: To delete a specific notification, hover over or tap on the notification you want to delete. You should see an option to either "Mark as Read" or "Delete" (the exact wording may vary depending on your device and the type of notification). Clicking or tapping on this option will remove the notification from your list.

5. Clear All Notifications: If you want to clear all notifications at once, look for an option to "Clear All" or "Mark All as Read." Clicking or tapping on this option will remove all notifications from your list.

6. Repeat if Necessary: Repeat the process for any other notifications you want to delete.

It's important to note that while you can delete notifications from your list, you can't undo this action. Once a notification is deleted, it's permanently removed from your notifications history. If you accidentally delete a notification, you won't be able to retrieve it later.

Additionally, deleting notifications only removes them from your own view. It doesn't affect the notifications received by other users or any actions associated with the notifications (such as comments or likes on your posts).
