A note on the Chrome Plugin “Fast Delete Messages” for deleting all Facebook Messenger Messages without deleting the conversations


Recently, we used the “Fast Delete Messages” on Chromium browser to delete all messages of a Facebook Messenger account without deleting the chats themselves.

To our surprise, we noticed two observations:

  1. The plugin worked extremely fast!
    We thought it would take a few minutes (as it would delete messages one by one), but it finished in less than a few seconds in reality.
  2. After the plugin finished, the list of conversations was empty!
    Initially, we thought a bug was in the plugin, and it had deleted all conversations.
    Following some research, it appeared that the conversations were not deleted, but Messenger hid them!
    We verified that the conversations were hidden as whenever anyone would send a message in a conversation or group chat, the conversation would appear, and it would work normally.
