When using FF ( v. 16.0.2 ) on a particular website, I try to fill in a special mail form available on this site for asking questions not available in the FAQ list. After writing down my question the form does not allow me to go to the next step and thus preventing me to send this request mail . I tried Internet Explorer I'm using as spare browser from time to time and with this browser no problem whatsoever ( IE v.9 ) Anybody suggestion to overcome this problem is very much appreciated
