As we all know, Facebook chat application implemented a major update and changed how the said chat application behaves. Many Facebook users are crying out loud to Facebook developers to give them some hint or pointers how to permanently delete their Facebook chat history both at the chat application and messages inbox.
Today, while I am checking out and testing out ways to permanently delete Facebook chat history from the Facebook chat application itself and permanently delete the messages from my Facebook messages inbox as well, I find this solution the best of them all. It is fairly easy to do and easy to follow. The below steps will just take you 3-4 minutes to complete (oh that depends on your internet connection by the way, it may take less than that for other countries with faster internet speed, yeah I am kinda ranting about our internet speed in here).
Here are the exact procedure, along with their corresponding images for you to be able to permanently delete Facebook chat history – both at the chat application and messages inbox.
Step 1). Click at your friend’s name (the person whom you have conversation with and you wanted that conversation deleted forever) from the chat application window.
Step 2). Click the gear icon you see from your friend’s chat window. Click see full conversation. This will bring you to your messages inbox wherein your conversation with your friend is being stored and saved.
Step 3). Then click action. Click delete messages. Click delete all. Done.
After doing the above steps, Facebook will take you into your messages inbox with a blank page.
You can check if the above steps works for you by doing the step 1, 2 and 3. If it works, Facebook will simply display a page containing the message “Send a message to start your conversation with [Your Facebook Friend's Name].”.
Hope you find this one helpful and informative. Please share this post to your followers and friends.

Nice one! With the many changes in FB, I can’t keep up.
True that. Feels like changes are made daily! Thanks for the comment!
If I delete a message and/or the conversation history from my chat/message box is it also deleted from the chat/message box of my friend?
Woow .. facebook just getting interesting! great changes began to be made by FB incontestably other social networks.
It’s a bit inconvenient that we don’t have the option to erase multiple chat messages with different people at one time, you really need to go to one specific conversation and erase all from there.. I hope the next update will provide us with the option to delete multiple messages at one time..
I am hoping for the same feature as well. Thanks for the visit Ane.
that works, great! thank you!!
this is handy if you want to get rid your fb history:)
