User Reviews
Thank you for making this. I was worried I'd have to keep a tab open on FB itself for Messenger once they turned off the dedicated Messenger site and its associated extensions would no longer work. This is perfect timing, much appreciated.

High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.
