This is a minor update to the Helvetireader 2 extension as a Safari 5 extension. It is signed and written by me ([email protected]), but the original work was done by Hicksdesign, and they deserve mad props for it.
As far as I know, this is the most straightforward way to actually pass a preference from your extension preferences to an injected script.
Thanks to tobstone@github for adding .de to the list of supported domains.
