Great addon, Greasemonkey with very nice extras. And now Greasefire is compatible with it.

If you're planning to use Scriptish 1.1.3 on a FF with an es-ES locale, there's a bug in the chrome.manifest file, where it says:
... locale/es_ES/locale ...
it should say:
... locale/es-ES/locale ...
This way you won't have problems opening the addons manager the first time you open it each time you restart FF. Or you can wait for a new version or use the last Scriptish nightly build:
