Hello every one today i'm going to teach you how to see when ur frnd was active on fb
REPLACE WWW with m.fb.com and open messages now
open m.fb.com now in ur PC and now you can check when the person was active here in the below picture the person was active 15minutes ago and this is also possible to look in ur mobiles too because this will show only in mobile version to view in the PC version you should replace WWW with M(M means mobile version)
