@korfob, I have tried both Chrome (latest), FF, Edge and my default Vivaldi. All work, internal page navigation and external links.

there was a fairly recent Windows update - try your machine with a cold reboot.

On my Android phone, after a second the Accept/Decline buttons disappear and the page has a grey overlay.
I think you are probably blocking pop-ups in your browser and are then stuck with this blocking links and scrolling.
