I don't use FF, and only go to perldoc when I want to post a reference as I have it all locally. Opera has a button(*) that just disables all the CSS which when clicked gives me a nice black on white, full width, basic html page with good size and readable fonts.

But it does bug me when authors break basic html stuff, and force everyone else in the world to work out how to compensate, just so they can play a few stupid tricks and look 'hip'. It's just style over substance.

(*)It works wonder on many sites, microsoft, the beeb (though it can't correct for their insistance on using fixed width tabular formatting that only uses half of my screen). And many more are vastly more readable and useable after that simple click.

I also get bugged by these little footnotes that show up:

This page is best viewed in an up-to-date web browser with style sheets (CSS) enabled. While you will be able to view the content of this page in your current browser, you will not be able to get the full visual experience. Please consider upgrading your browser software or enabling style sheets (CSS) if you are able to do so.

I don't go there for some art-fart's idea of a "full visual experience"--I go there to read the news!
