Johannes Schellen's Themes for the Seamonkey Suite
Pinball:
The current version is 2.3.1, published 2011-09-10. This version is compatible with the SeaMonkey Suite 2.3.x. I have disabled the version checking so that the theme won't be disabled every 6 weeks, for no good reason, thanks to the new Seamonkey release schedule. Unfortunately this also means that Seamonkey will no longer warn you if the theme actually isn't compatible with a new Seamonkey version.
