Want to see what Google, Digg or Slashdot looks like in newspaper style columns? Multicolumn extension uses Firefox’s implementation of CSS3 multi-column layout to convert Digg’s stories to pretty columns – pretty that is if you have the screen real estate! You can configure things to apply columns to other sites as well, but the results aren’t always so pretty. Notice that there is also a Greasmonkey script which could help you creating the same effect. Get the extension from http://multicolumn.mozdev.org.
