Just to be clear – I am not using the Chrome version. I cannot use the Chrome version because it does not allow me to display the Menu bar at the top, which is absolutely necessary to us for business purposes and being able to open saved/archived .html files in the Brave browser. I have not found any way in the Chrome version to turn on the Menu bar at the top, and there is no function in the options menu for opening archived files in the browser. I have posted about that issue before, but I not had any response or seen any movement on it.
So the website blocking issue is occurring for me in Muon 8.1.8.
