Use the version of Google from your victim's country, for example, if your victim is from France, use (google.fr) and manually write PayPal to google.fr and we will adjust the VPN here too.
Use a special domain on PayPal (so if the victim is from France, use PayPal.fr)
Enter your username and password manually without copying and pasting. (also important because Pay Pal understands when you insert and when you enter manually)
Open the payment page in normal browser mode and the payment page in incognito mode.
In normal mode, a confirmation window will pop up, but in Incognito mode it will skip, so be sure to continue working in this mode.
