One day I was browsing my messages on Facebook, I was deleting
some #FB messages by clicking on “X” button but later on I found a group of
hidden folders in message section. And I found that all my deleted messages were
there, 3 year old messages. So I tried to delete all those messages but Facebook
won’t allow you to do this E-A-S-I-L-Y.
I have searched for solution but no use; there are no Shortcut Commands to delete those messages permanently. There is no Software
or Browser Add-On to delete those messages. There are some websites which claims that by installing their script in their browser using grease monkey can help in deleting messages, Google chrome add-on but nothing is useful.
There is only one solution “Delete Whole Conversation” using Facebook options
Click on Messages – Select Message you want to delete – if you click on “X” button, message will shift from Inbox to Archive. So don’t click on “X” button – click on Action Button on right corner – Select Delete Conversation”.
