The latest 3-4 weeks the background on one particular webpage has started to be visible and I have tried without luck to find a way to block it. I have used Firefox developer/Inspector but I do not know what to look for. Are there somebody that can guide me in the right direction what to look for - properly som CSS stuff - the page is https://nyheder.tv2.dk/ which has a static clickable background visible.
Thanks for quick reply.
I have verified that DNS over HTTPS in Firefox is disabled. I have tried to block any for that domain related entries seen in the log at load time. No result in blocking the background image. I'll try your suggested AdamOne Assistant.
