Post instructions for creating this Extension
Post introducing v2
Ideas and Code Reference from KB2A Tool
Update : Extension is available on the webstore, go to the link and install it directly: Chrome WebStore
Or you can install it manually
When accessing Facebook or messenger, the extension will run automatically
RVDFM will listen and save every incoming and outgoing message, or when you view someone's message RVDFM will also save it for you.
When someone retrieves a message , RVDFM will check whether the message has been saved or not. If it has been saved, RVDFM will display the saved content to you.
NOTE : Currently, messages between facebook.com and messenger.com are not synchronized , so RVDFM will save messages in these two pages separately.
Note: If you installed the tool before the most recent update listed below, you should download and install it again to be able to use the latest functions and avoid errors.
