In the example I gave, I was making the point that FF itself broke standards. The page called for <div> ... <b> ... </div><div> ... <b> ... </b> ... </div> which is incorrect. But FF compounds the error by allowing the bold instruction to cross into the next div, which is against the standards. I wasn't suggesting FF should correct the error.
Except that in FF's dropdown the links are in a higgledy-piggledy mess.
Not all of us. My point is that by resizing all fonts, it encourages the use of images instead of text.
For example on one of my sites I have a header div with a background image on which is superimposed a four-word 30px description between <h1> tags. It meets usability standards. But FF can resize this txt so that it wraps, but FF doesn't resize the div, but lets the text spill out into the following div. If it was a commercial site I would be forced to make this title into a gif.
The problem with FF is it's a half-smart browser. It takes a lot more effort to create a browser with the flexibility and usability of IE than it does to create a purely 'standards-compliant' browser. It's the soft option.
