Hi Carlos,
I’m just realizing now that, because I always open Chromium in incognito mode, my browser always blocks third-party cookies. When I try the experiment I linked to above, I see that the browser is blocking two third-party cookies. Regardless, the experiment runs smoothly
My questions were meant to be about potential problems with running experiments/opening a webgazer page (eg. this one), not about cookies or the TypeError message specifically. That being said, we’ve established that blocking third-party cookies does not prevent you from taking other experiments, if you were able to take the self-paced reading experiment while 6 third-party cookies were blocked
