[NTLUG:Discuss] Mozilla/Firefox HTML validator

[tr_data1]

My children's school system (Coppell ISD) has been tinkering with creating
website(s) for newsletter/grades/etc info. They call it the "portal". The
problem is, I am forced to use InternetExploder, due to some incompat. in
their login logic. It's at the bottom left of north.coppellisd.com, where you
will see "My Portal" caption with a user and password text fields.

When using IE, entering uid/passwd and pressing "Login", sends me to a
different page with the info I am trying to access. On Firefox/Mozilla, it
goes to another login/passwd screen. Entering that again just puts you
back to the same secondary login page. Anyway...

I am looking for a tool that I can point at a web page to determine what
is non-standard (IOW, M$ specific) code. Is there such a tool? My guess
is that their page was created by an M$ tool and of course creates buggy
or otherwise propriatary HTML.
