Web Compatibility Support • Re: Paypal.com Stuck at Security Check

Thanks for the suggestion. I think I've cracked it. It's an nmatrix/ematrix setting "Spoof HTTP referrer string of third-party requests" which I think is turned on by default? Even if I disable filtering from via the toolbar icon, the "Spoof HTTP referrer string of third-party requests" setting is still active. Unticking this has solved issues with another website that I couldn't view properly as well, so I'll leave that unticked now.
