Greasemonkey, one of the most important add-on’s for Firefox but it is currently not supported in 4.0+ versions. For those who don’t want to wait for a working add-on of greasemonkey, here’s – Scriptish.

Scriptish is a fork of Greasemonkey, it can do everything Greasemonkey does (but it’s only for Firefox 4+) and a few more features that even GM doesn’t have.

Complete list of features:

User scripts are upgradable.

User scripts can have icons!

Recognizes Google Chrome’s @match pattern

@author – displayed to users in the addon manager

@contributor – displayed to users in the addon manager

@homepage or @homepageURL – displayed to users in the addon manager

@icon or @iconURL – Include a icon for your user script which is displayed in the addon manager and for notifications from the script.

@screenshot – displayed to users in the addon manager.

@match – a include pattern introduced by Google Chrome user scripts.

@noframes – a simple way to prevent a user script from running in iframes.

GM_worker – use a Worker within user scripts.

GM_setClipboard – save data to the clipboard from a user script.

GM_notification – send a Growl style notification to the user (screenshot below).

Another worth-mentioning feature about this add-on is the way it uses Javascript Modules of FF in a way that only loads code into memory that will actually be used i.e. JSM would allow Scriptish to use much less memory and improve performance as compared to Greasemonkey when a user is using multiple windows, and on startup because less JS would need to be loaded at startup.

I’ve been using Scriptish and Most of the GM scripts work with it. Actually I haven’t found any incompatible scripts on though I’m sure they exist.
