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.

Facebook gives hints about what a picture contains on the ‘alt’ field

Just a fun fact:

Facebook posts some of the information that it automatically derives from user pictures in the alt field of the pictures.
Below we post two samples from a stream that demonstrating this feature:

In the first one we can read in the alt the following Image may contain: 1 person, smiling, closeup.

In the second one we can read in the alt the following Image may contain: 1 person, sitting, pool, sky and outdoor.

We can see that in both cases the information is pretty much valid.
