I have noticed this problem as well, but only when I use Firefox. I use a Windows 7 system, and have all the latest versions of Firefox, Safari, Chrome, Internet Explorer, and Opera installed.
Firefox: 73.0.1 (64-bit)
Safari: 5.1.7 (7534.57.2)
Chrome: 80.0.3987.122 (Official Build) (64-bit)
Internet Explorer: 11.0.9600.19572
The problem occurs ONLY with Firefox. When I use any of the other browsers, my visits are ignored as expected when the “Ignore my visits” cookie is set. I UNDERSTAND fully that this option is browser-specific.
