Well, if it generally works on modern browsers except Firefox in 
"standards mode", the question "why fix it?" is even more emphatic.

Oh, why?

If pages now work in "quirks mode", then there is seldom any good reason 
to spend time in "fixing" them to work in "standards mode". Part of this 
is the complexity of "quirks mode". There can be a wide range of 
problems lurking around if you switch to "standards" mode. It is much 
more productive to concentrate on keeping the content OK and on creating 
new pages (and in the latter, you would of course use as 
"standard-conforming" techniques as possible).

(If, however, someone is really considering the effort of converting an 
existing site from "quirks" to "standards", then he could consider 
changing document.all.formname to document.formname. But this would be a 
rather trivial part of the job.)
