[iframe] Overcoming "Display forbidden by X-Frame-Options"

<form target="_parent" ... />

Using Kevin Vella's idea, I tried using the above on the form element made by PayPal's button generator. Worked for me so that Paypal does not open in a new browser window/tab.

Update

Here's an example:

Generating a button as of today (01-19-2021), PayPal automatically includes target="_top" on the form element, but if that doesn't work for your context, try a different target value. I suggest _parent -- at least that worked when I was using this PayPal button.

See Form Target Values for more info.
