No it doesn't. At least not with Firefox. Just use
View --> Page Style --> No Style
But as for the other complaint elsewhere in the comments, about light gray text, unfortunately Firefox can't help with that. Normally such misguided text is countered with
but in this case the gray is unfortunately in images and not text.
And it gets even worse for the light gray text. OS X Accessibility has a setting to "Enhance Contrast". But in this case the gray is closer to white than to black, so all that "enhancing" does is make the text even lighter!

Sigh.
