I’ve been re-reading Mark Pilgrim’s 30 Days to a More Accessible Weblog and updating various bits on this (relatively new) blog. One thing he doesn't point out, particularly in day 26's column, is a combined application of day 9's and day 14's tips that will help Bill (and other Mozilla users): adding a title attribute to the <link rel="stylesheet"> tag. This allows them to completely turn off the styles that have been defined in that sheet using the “View > Use Style > Basic Page Style” menu item—fonts, colours, sizes, everything as you've told your browser to display it. (The W3C refers to this in the HTML 4.01 Specification as defining a preferred stylesheet.)
Oh yeah, a sample:<link rel="stylesheet" href="styles.css" title="Default site styles" />
