Stack Overflow Unofficial Patch (SOUP) od Ilmari Karonen

The Stack Overflow Unofficial Patch (SOUP) is a project to collect various minor client-side bug fixes, work-arounds and usability improvements for Stack Overflow and other Q&A sites on the Stack Exchange Network into a single user script. Now, for your convenience, it is available as a Firefox add-on, as well!

The intent of SOUP is not to make any substantial or controversial changes to the Stack Exchange user interface, but to fix minor problems and omissions that the SE developers have overlooked or haven't got around to fixing yet. By combining these minor patches into a single package, they become easier to install and maintain.

For more information, including a list of the included fixes, see the SOUP home page on Stack Apps and the SOUP repository on GitHub.
