When I started using Firefox with the Temporary Containers extension I would get absolutely bombarded by Cloudflare's captchas. To the point where if I clicked on a search result that sent me to a captcha, I would just close the tab and click the next result (which often resulted in another captcha, rinse repeat). That's when I realized just how big Cloudflare had gotten.

I still use Temporary Containers and lately, I've noticed a sharp decline in these Cloudflare captchas. I don't know if its because people are moving away from them, or Cloudflare just found a better way to finger print me.
