CTRL+SHIFT+S or Why Every Firefox User Should Install the Webmaster Toolbar

Main stages of readability on the web:

1. The web is created, and it is good
   No no bgcolor, no line-height ... nothing to get between a reader and the content
2. Netscape 3 & 4
   Netscape 3 & 4 were a massive setback to readability and the original, considered, design of the web.
3. Widespread Use of CSS on many non-CSS Nerd sites
   Many sites now use CSS as the primary means of laying-out and styling content on their pages. This is a terrific thing because...

...hitting CTRL+SHIFT+S in Firefox with the Web Developer Toolbar installed allows you to quickly disable off all the CSS on the page that is making the text too small, too big, too narrow, to faded, justified, and all kinds of other attrocities that make text look like anything from a page in a book.
