Welcome to the Scriptish wiki!
Scriptish is a fork of Greasemonkey, which was the first Firefox extension to allow users to modify webpages with user scripts. Greasemonkey had long supported Firefox 1.5, and recently decided to raise the minimum supported version of Firefox to 3.0. Plenty of legacy code still exists, however, and it has reached the point where Greasemonkey needs a complete reorganization. But unfortunately, development of Greasemonkey is incredibly slow for bug fixes, let alone code base refactoring or the addition of features. This is why I decided to fork Greasemonkey and start something new.
