To delete messages on Facebook, you will need to open the private message, go to alternatives and begin picking the message you want to delete. If you have numerous messages, the process can be very time-consuming. Otherwise, you can just eliminate the messages from the message list, however doing this will not remove the message permanently. Instead it will be archived, and will come back when the person sends you a brand-new message.
Here's where we generate some help i.e. 'Facebook Quick Delete Messages', an extension for your Chrome web browser that will allow you to erase Facebook messages with a single click.
The procedure is easy. Open up your Chrome web browser and navigate to the plugin. Click "Contribute To Chrome" in order to download/install the plugin. It presently has over 82,000 users and I discovered it to be virus/bug-free since two weeks earlier, so I can highly recommend it.
How To Erase All Facebook Messages
Once it's installed, just sign into Facebook. Open the full messages window and click the plugin icon that rests on the far right of the address bar.
Then click "Introduce". It will erase all the messages on that entire page. If you have a lot of old messages you might need to scroll down and click Release a few times until they're all gone.
However within a couple of minutes you should be rid of all your old discussions, and they will not reappear when the person messages you again. You'll have a tidy slate!
