Hm ok, Is there a particular way to transfer cookies from mobile device to PC?The best of the best things you could do is use that account from the same internet connection and same device (cookies are stored on that device and cookies are very important if it comes to using other people's accounts) that the account owner used before.
If you can't use his device (laptop or pc or whatever he use) then maybe just copy his cookies and put them on your device and use the same network that he uses, FB will see different browser fingerprints etc but cookies gonna help you![]()
For cookies, can't I just visit big brand stores, news pages, etc to build cookies? Unless what you mean is to have identical cookies.
