A port of Anal Volcano's excellent Fancy SA Forums Chrome extension. Performs a major restyle of the Something Awful forums interface to make it not ugly.
This is a new "jetpack" extension, so it can be installed, updated, and removed without ever needing to restart Firefox.
Right now, this is a very preliminary direct port of the current Chrome extension. There are no options, just install and refresh your SA forums pages to see the effect. This may change in the future as the main extension develops.
For more information, see the original thread.
