Facebook Messenger is a fairly simple app on the surface, but sometimes its simplicity can make it a little confusing. In this guide, we’ll address some common problems experienced by users. How can you delete all messages at once? Is there a way to recover deleted messages? What about blocking? We’ll handle all of these topics and more below.
1) Deleting All Messages : Unfortunately, there isn’t a way to delete all messages at once from your phone. That being said, here’s how to delete full conversations or individual messages on mobile Messenger. If you don’t have too many, just rinse and repeat these steps.
From Your Phone : On iOS, just swipe to the left on any conversation on your home screen and select delete to remove the whole thing. On Android, hold down on the conversation and select delete. For individual messages, you can go into a conversation, hold down on the specific bubble and select delete. Rinse and repeat until it’s all gone.
From Your Computer: One of the only known ways to delete all messages from a Facebook account is to use the Facebook – Delete All Messages extension for Google Chrome. Once you have Chrome, try these steps.
Click the “Add To Chrome” button and then “add extension”
After that, a small blue icon will appear in your browser’s top right corner.
Click it and select “Open Your Messages”
Log in with your credentials and select “Begin Deletion.” The process might need to be performed twice.
NOTE: This method is true to its name and will delete every message you have. This includes those that are archived. It’s also not officially sanctioned by Facebook, so it may not work as the service is updated. It’s functional at the time of writing.
