I'm using an ad blocker (uBlock) but I don't mind disabling it for web sites I want to support. However, the site still tells me I'm using an ad blocker when I'm not. I've reloaded the site, even restarted the browser. Maybe it's some option I've ticked in the browser preferences (Firefox), but I don't think so. I have tracking protection, but that doesn't interfere with ads on other sites.
