Hi there,
We don’t offer that ability out of the box because of how Give needs to interact with PayPal directly. As it is now, the donor is passing information from the Give form to PayPal. The Give form goes into “pending” mode until that redirect completes. If it doesn’t complete, then the form just keeps spinning as if nothing is happening. Then after the donation is complete at PayPal.com, they are redirected back to your site to the Donation Confirmation page with all the correct information. That whole process works best when it happens within the same browser window and can get a bit messy if it happens in multiple tabs.
You can add a target="_blank"
attribute to the form tag but that would require custom code.
Let me know if that makes sense and whether you have additional questions. Thanks!
