I'm having the same issue, and it's very frustrating. Seems to be that having 3rd party cookies and 'do not track' in Firefox makes it worse.
Running a naked browser in a VM and solving a few will get past the issue for a while... then it will start asking you as well after you've viewed a few dozens of pages, even in a totally stock, insecure browser.
I'm wondering if Curse has cranked up the security settings on their Cloudflare dashboard for some reason. Setting to "High" or "I'm Under Attack!" will very quickly cause problems like this, in my experience.
