Hi
browser is used for recaptchav1 via browserloop
and
recaptchav2, sweet captcha, are you a human, confident captcha, and geetest via browser solver
switching browser solver off via checkbox does not stop support via browser entirely, browser loop only has advanced setting.
you need to configure firefox to auto close tabs, by default it does not do this.
