Forum Moderators: not2easy
firefox doesn't seem to respond to the style= fixed command in css.
I'm not sure what "style=fixed" is, however, I can tell you that AFAIK (and thankfully), there is no way to make FF fix a font size so that the user resize option in the browser doesn't work. Allowing this would actually defeat the purpose of the browser's font resizer, which is to put the control in the user's hands, not the designers.
If you don't want the header size increasing, make it an image and use an image replacement technique. (Note that in Opera, and hopefully in the future more browsers, even this won't work. Opera's Zoom feature allows you to increase the size of everything, including images.)

taking my ability to keep my presentation from being skewed is taking away my rights
You can retain control over your layout by creating an image of what your page looks like and serving that image to the user. Otherwise, the page will consist of html elements, many whose appearance is simply beyond your control. OS's, browser quirks, default settings, installed fonts, user stylesheets ... the list goes on ... all stand in the way of your page appearing to every user in exactly the manner you want.
the header is already quite large enough
You're missing the entire point behind accessibility, which is that you (designer) don't have any idea what font-size is "large enough" for me (user) to read.
it should be my choice as to how it is viewed
See msg#7 in this thread [webmasterworld.com] for why the above line is actually irrelevant.

But I still think that instead of a browser just resizing the text it should incrementally resize the "whole" page.
But that would mean scrolling the whole page, not just the part someone is trying to read.
It's not easy packing an all the accessibility issues when you are just getting up to speed with this stuff. But there is some joy in resizing your pages and watching them almost magically reflow to fit the space available. Like watching a very clever dog do tricks, and you know you are the one who trained him.
