Not infinite but I do get a couple in a row as it seems to redirect around a few domains (.today, .is, .ph)

If you change one or the other does it fix it?

And what extensions are you using? Anything in firefox that would exacerbate the problem?

Tte prove that you are human thing work with a mouse movement tracker, if you move the mouse to straightline or calculate movement to the checkbox, the algorritm supposed a bot. But normally this issue you have is due to some extension, browsersetting or security soft. In Vivaldi I checked it in a guest profile, this putt the browser to the default settings and without extensions. I think in Firefox there will be a similar methode to check it, otherwise desactive the extensions one by one and clear the cache.

I am not getting prompted any captcha when I visit the site.
