This is a somewhat hacky bookmarklet for sweet-justice. It will justify all <p>s on a page when accessed, yay.

Until I make something a bit more proper (bah, morning classes!), right-click on Firefox's bookmark bar (I really have no idea if you can do this in other browsers), and make a new bookmark. In the location, copy+paste the content of justify.js. Click your fancy new bookmark when you want to justify a page. Hooray.
