Yes, you can slightly edit a file in plugin folder to do this:
Step 1: Go to : paypal-donations.1.8.1\paypal-donations\views\paypal-button.php
Step 2: Find the code “$paypal_btn .= ‘<input type=”image” src=”‘ .$button_url. ‘” name=”submit” alt=”PayPal – The safer, easier way to pay online.” />’;”
Step 3: Please replace the above code with:
“$paypal_btn .= ‘<input formtarget=”_blank” type=”image” src=”‘ .$button_url. ‘” name=”submit” alt=”PayPal – The safer, easier way to pay online.” />’;”
